How many bonus types are there?
Are there any rules to what casters can affect which bonuses?
It all comes down to stacking rules..
I have a creative player in my game that would like to create new spells and I would like to make a ruling on how each class can affect the game.

While I can agree that some bonuses fit some casters better than others. Morale for Bards etc....The only bonus type that I would place a hard cap on whos spells can grant it would be Sacred and Profane, limiting those to divine casters. Other than that I dont see why a cleric or wizard (specifically an enchanter) shouldnt be able to grant a morale bonus, or why a druid couldnt grant an Insight bonus as long as the spell was thematically appropriate for their class.

Here in this thread.
But that just points you to this d20 SRD thread.
James Jacobs once said that it's unfortunate that this list got left out of the core rules, so I guess it's official, it's unfortunately not in the book. Might as well use the d20 SRD then. I'm mostly sure all those same bonuses are applicable in the same way in Pathfinder.
As for limiting which classes can use which bonuses, that might get awkward. For example, if you rule that a certain class cannot cast spells that create a certain bonus, you might end up going through all of the spells, one at a time, and changing bonus types on some of them to accomodate this ruling. Or even more painfully, moving a divine spell to become an arcane spell, or vice-versa, if necessary.
And don't forget that new spells are coming out all the time in the various APs, Companions, and other sourcebooks.
Instead of limiting effects by class, why not limit effects by, uh, effect? By that I mean, if a spell's effect is to magically enhance some characteristic, then that should be an enhancement bonus regardless of which class casts that spell. If a spell helps you avoid fire damage, then it should be a resistance bonus, regardless of who cast it. And so on.
When a "creative" player decides to create a 1st level arcane spell that fills him with hope and elation to grant him +4 AC as a 'morale' bonus, and then promply stacks it with Mage Armor and Shield for a net +12 to his AC, we might have broken the system. That sounds a little bit over the top. Especially when he researches another new spell that gives him a +4 'luck' bonus to his AC, and another new spell that gives him a +4 'insight' bonus to his AC. It's even possible that you as a DM ruled that wizards should be able to cast spells with morale, luck, and insight bonus types, so he would be entirely within your ruling to use these bonuses. But +20 to his AC at level 1 is ridiculous (and more ridiculous when he takes Craft Wand and makes wands of these spells to free up his slots).
You have to draw the line somewhere.
Drawing the line as a class restriction won't work. A "creative" player will just work within your class restrictions, as in my example.
So you should draw the line as an effect resriction. Spells that increase your AC are either 'armor' bonuses that don't stack with other 'armor' bonuses, or they are 'deflection' bonuses that don't stack with other 'deflection' bonuses. If you do allow other bonus types to be applicable, then they should give smaller bonuses or require higher level spells, or both.
