So which bonuses stack and which do not?
Like if I have a Tiefling with the Scaled Skin Trait (+1 natural AC) and then later take Armor of the Pit (+2 to natural AC), do all those bonuses stack to Natural AC?
And what if he gets a magical bonus to natural ac? would that stack with his non magical bonus to natural ac or no? Otherwise then an Amulet of Natural AC +1 would be useless to a Tiefling with Armor of the Pit wouldn't it?

Natural armor bonuses don't stack, but many of the things that grant "natural armor" actually grant an enhancement bonus to your natural armor (which still don't stack, but an enhancement bonus to your natural armor isn't a natural armor bonus).
(Also, there's no such thing as "natural AC".)
I can't find a trait called "Scaled Skin" -- could you link/quote it? I found Tough Skin, but that has nothing to do with natural armor.
Armor of the Pit grants you a natural armor bonus; as stated above, natural armor bonuses don't stack.
And what if he gets a magical bonus to natural ac? would that stack with his non magical bonus to natural ac or no? Otherwise then an Amulet of Natural AC +1 would be useless to a Tiefling with Armor of the Pit wouldn't it?
No. An Amulet of Natural Armor +1 grants you an enhancement bonus to your natural armor; it's basically adding a +1 to whatever natural armor you already have (provided that natural armor doesn't include any other enhancement bonuses).

Scaled Skin and Armor of the Pit unfortunately do not stack to give you a higher armor bonus, Armor of the Pit just gives you resistance to the two resistances you gave up for Scaled Skin.
Either of those abilities would however stack with an Amulet of Natural Armor, since it provides an Enhancement bonus to your existing natural armor.

Ah, it's an alternate racial trait, not a trait.
It increases the bonus to +2 instead of the +1; they don't stack for a +3.
If you read the special, it doesn't even do that. Taking Armor of the Pit when you have Scaled Skin gives you a completely different effect than taking it without that trait.

There's no question of them "stacking" or not. Take a look at the "Special" line:
If you have the scaled skin racial trait, you instead gain resistance 5 to two of the following energy types that you don't have resistance to already: cold, electricity, and fire.
Note that it says "instead". Even if it granted you a +2 natural armor bonus as well as the resistances (it doesn't), they wouldn't stack.

I see now what it does though. So if you have Scaled Skin you have a +1 to Natural AC AND 5 vs one type of energy. If you also take Armor of the pit later on then you will gain 5 vs two other energy types and still keep your +1 Natural AC but your natural AC doesn't go up to +2 or "stack". Still decent but I lean towards the +2 to natural ac instead...

Well, this is slightly annoying.
So, to clarify - a Kobold (who has a natural armour bonus of +1 at first level, assuming no feats) who takes the Draonic Bloodline up to 3rd level (thereby gaining a bloodline natural armour bonus of +1) would still only have +1 natural armour, because both are bonuses?

I'm pretty certain that these bonuses do stack. Natural armor is kinda weird that way, but racial/class abilities that grant natural armor tend to stack. Only things that grant an "enhancement bonus" to armor do not.

You could skip the NA +1 for levels 1 and 2, and instead get resistance 5 to an element of your choice with alternate traits.

There is a monster feat that increases natural armor by one every time you take it...
I did not even know that Improved Natural Armor could be taken multiple times.
Now I kinda want to roll up a guy just for lulz who's like a Monk (MoMS)/Fighter who pumps Wis and Dex to the exclusion of all else (besides the 13 Con) and only takes Improved Natural Armor except for the Crane Style feats.
Maybe a Kobold unless someone knows another good race with Nat Armor. Wait, actually, Scarred Hobgoblin, get that Natural Armor without taking the hit to Str so he doesn't suck as much, and more points leftover to bump Wis/Dex. Unarmed Fighter for the other free Crane Feat.
Lessee if that's possible with a 20 PB.
Dump: Int, Cha, Str to 7, Con 11 = 11 points
Dex + Wis requires 34 points for 18 in both, 31 available.
Dex = 18 = 17 points
Wis = 17 = 13 points
1 point left, nowhere to put it.
End up with 20th level:
Str: 7
Dex: 24
Con: 13
Int: 7
Wis: 18
Cha: 7
Bump Wis at 4, Dex at 8, 12, 16, 20
So that's what, +18 AC from Improved Nat Armor, +1 normally, +4 Wis, +7 Dex, +5 fighting defensively for a total of 35 with no magic items? Plus the ability to deflect a hit once per round.
Completely useless at everything else, but man would he be hard to hit.

My understanding of natural armor:
A natural armor bonus does not stack. A Kobold with Draconic Bloodline has +1 Natural armor from his/her race and (at level 3) +1 Natural armor from the bloodline. They don't stack, so it is only +1. Continuing along the bloodline, when the sorcerer bonus goes up beyond 1, that begins to take over.
However, there are also improvements to natural armor.
Benefit: The creature's natural armor bonus increases by +1.
Natural Armor Increase (Ex): As his skin thickens, a dragon disciple takes on more and more of his progenitor's physical aspect. At 1st, 4th, and 7th level, a dragon disciple gains an increase to the character's existing natural armor (if any), as indicated on Table: Dragon Disciple. These armor bonuses stack.
In this case, a Kobold Sorcerer who took Improved Natural armor would have a +1 improvement to it's natural armor. I would assume that you can choose which to apply it to (in other words, the higher one), but I could be wrong on that.
Either way, a Sorcerer/Dragon Disciple, for example, gets their natural armor bonus of X, with an increase to it of Y from Dragon Disciple.
Last but not least, is an enhancement bonus to natural armor, such as Barkskin and Amulets of Natural Armor.
The effect grants a +2 enhancement bonus to the creature's existing natural armor bonus. This enhancement bonus increases by 1 for every three caster levels above 3rd, to a maximum of +5 at 12th level.
...giving him an enhancement bonus to his natural armor from +1 to +5, depending on the kind of amulet.
These are applied similar to the increase, but do not stack with themselves. So if you have a Sorcerer with an amulet of natural armor of X, he may also have an enhancement bonus of +Y, which will go on top of it. If he also gets barkskin placed on him, he will use the higher of either of those enhancements to his Natural Armor.
Summary:
Natural Armor Bonuses: Don't stack.
Increases/Improvements to Natural Armor: Stack
Enhancements to Natural Armor: Don't Stack
Total Natural Armor Bonus = Highest Natural Armor Bonus + All Improvements to Natural Armor + Highest Enhancement to Natural Armor
Example: Kobold Sorcerer 9/ Dragon Disciple 7 with Improved Natural Armor Feat, Amulet of Natural Armor +3, and Barkskin at caster level 12.
2 Natural Armor Bonus (1 From Kobold OR 2 from Sorcerer 9) + 4 Improvement (3 from dragon disciple 7 AND 1 from Improved Natural Armor feat) + 5 (3 from Amulet of Natural Armor OR 5 from Barkskin)
You could also boil it down to: 6 Natural Armor Bonus(2+4, as above) + 5 (Enhancement, as above)
Total makes for +11 Natural Armor Bonus to AC.
Disclaimer: I am not entirely positive on all of this, but it is my best understanding of it. If anyone knows better, please let me know.

I'm personally inclined to say it is a regular natural armor bonus(i.e. one that would overlap with existing NA).
Comparing Monstrous Physique with the Large evolution for a summoner's eidolon.
...and a +2 natural armor bonus.
...and a +2 bonus to its natural armor.
Though the evolution apparently doesn't use a size bonus for its stats either. Regardless, not entirely sure. Related discussion here. (And the circle of linking is complete...)

I am making a Tiefling Dragon Disciple. The Way I am reading this is with Armor of the Pit, a +2 Natural Armor Bonus. This is racial so stacks with everything. Dragon Blood, eventual +4 Bonus, Dragon Disciple +3 Bonus that stacks with everything. Form of the Dragon II adds +8 Bonus that stacks with all of it. Druid casts Bark Skin, for another +4. Only thing that would not stack is a Amulet of Natural Armor and Bark skin. Only one will kick in which ever is highest. So in the end, 21 Natural Armor Bonus. Which is needed since Armor Would Meld into form. Could use Bracers of Armor +8, or go with Mage Armor for a +4. Toss in a Shield spell, and your talking 33 at max. Plus any Dodge/Dex/Wis(if a monk) as well. Certainly not the highest Armor one could come up with. I am figuring my Dex to be 24 at 20th level, and Wisdom would be 24 as well. So toss in another 14 to my Ac, for a grand total of 47. Will end up with no Dodge Bonus on this build. Though Could fight defensively and Combat Expertise for a bit more. Touch Ac is going to be weak though. Does this sound about right?

It's kind of funny. Basically, if it's a typed bonus to Natural Armor (like Enhancement, or Racial) it stacks. If the wording of the ability says it increases your natural armor, it stacks. If it says gives you natural armor, then it doesn't stack and you take the highest.
For example :
If an ability says you gain +2 natural armor, and it's not typed, that's the type that doesn't stack with anything else. So, the kind you get from your race (racial) is your base natural armor. If you had +1 Racial granted Natural Armor Bonus, and you got something that said it gives you a +2 natural armor, the untyped +2 overrides your racial bonus, being higher.
If you later got an ability that said it 'increases your natural armor bonus by +1', like DD does, then you'd have a +3 Natural Armor (+2 from the first ability, and +1 increase from DD).
Finally, if you put an Amulet of Natural Armor on, that's an enhancement bonus to Natural Armor, and it adds to your +3. So if it was a +2 amulet, your Natural Armor would be +5 total.

Dodge bonuses stack. Natural armor bonuses do not, unless they're in very specific ways (enhancements or other increases specifically to the natural armor). Much like multiple armor bonuses don't stack, but enhancements to a suit of armor do increase it.
To the best of my knowledge, Dodge is the only thing (AC related that is) that stacks though.

This might be helpful. Here is a list of Bonus Types and it specifies if they stack. WHY IS THIS NOT IN THE CRB?!

So which of these stack then in your opinion?
Armor of the Pit
Your fiendish traits take the form of a protective scaly skin.
Prerequisite: Tiefling.
Benefit: You gain a +2 natural armor bonus.
Dragon Resistances (Ex): At 3rd level, you gain resist 5 against your energy type and a +1 natural armor bonus. At 9th level, your energy resistance increases to 10 and natural armor bonus increases to +2. At 15th level, your natural armor bonus increases to +4.
Natural Armor Increase (Ex): As his skin thickens, a dragon disciple takes on more and more of his progenitor's physical aspect. At 1st, 4th, and 7th level, a dragon disciple gains an increase to the character's existing natural armor (if any), as indicated on Table: Dragon Disciple. These armor bonuses stack.
This spell functions as form of the dragon II save that it also allows you to take the form of a Huge chromatic or metallic dragon. You gain the following abilities: a +10 size bonus to Strength, a +8 size bonus to Constitution, a +8 natural armor bonus
AMULET OF NATURAL ARMOR This amulet, usually crafted from bone or beast scales, toughens the wearer's body and flesh, giving him an enhancement bonus to his natural armor from +1 to +5, depending on the kind of amulet.
I see no reason why Tiefling NA would not stack with Dragon Resistance, Dragon Disciple, or the Dragon Form. Since One is racial, one an EX power of a Sorcerer which is just increasing what you have already. as well as the Dragon Disciple. Dragon Form Spell gives one due to size in my opinion since you just grew to size Huge. Your getting a strength and Con boost as well. And Finally the Amulet, which is the only Enhancement bonus.
This makes a difference as I will be a cross blooded Sorcerer, so if the Bloodline does not stack with anything, then I would skip that and take the other Blood Line power at level 3. Or skip the Armor of the pit feat for something else. Will also have to make me rethink snake style and go with Crane Style, as if my Ac is going to be that much lower then Snake style may not come into play much. Where as I can always deflect an attack and take my one AOO. But I just do not think that makes any sense. I can understand Enhancement bonus's not stacking. I can understand wearing 2 armors wold not stack. But these are from different sources just increasing ones Natural Armor.

In fact if what your saying is true, then only The DD bonus and the Spell Dragon Form would be working out of these Bonus's. The rest are worthless. Or Would the Amulet stack as well since its an Enhancement?
At Best, your getting a +3 For DD
+8 For the Spell
and possibly +5 for an amulet. So either 11 or 16 for Natural Armor Bonus with this build.
