Hello, Anti Paladins take the fiendish boon ability at lvl 5. It comes in two forms:
You either buff up your weapon (like paladins do) or you get a "Fiendish Servant" as per summon monster III (in antithesis to the paladin's holy horse). As you level up summon monster III becomes IV, V and so on.
So my question is, how much do those "servants" serve you? Are they loyal? I mean yeah a fiendish animal could be loyal whatever, but what about a shadow or even worse a succubus. Do they do as they are told no questions asked, do they seek to betray you, are they a gift from the dark god you serve so their job is to serve you at their best of their abilities or are they bound to it and have to obey you while they loath doing so. Are they really there or are just manifestations of the creature just like from the summon monster spell. I'm not even going to ask about the profane gift so many threads about that.
To sum it up.
1. Loyalty and attitude against you.
2. Is the monster the boon or is the ability to summon the monster the boon (fluff wise). (Like, good job reaching level 5 of epic douchiness I reward you with a servant to aid you, please take your pick dont be shy or I reward you with the summon monster III spell from pg 352 from the Core Rulebook, keep up the bad work.
3. Can you summon demons if you serve devils and vice versa (roleplay wise).
4. Is the monster really there or just its manifestation.
I mean, it is a "Boon" and the monster is a "Servant" but these are Demons and Devil we are talking about here... so I'm not sure.

1. RAW, it's based on a summoning spell. They didn't make any changes to loyalty, etc. So its loyalty is "If you can communicate with the creature, you can direct it not to attack, to attack particular enemies, or to perform other actions." With that said, GMs are going to run it how they want, and you'll have plenty of input yourself. "Completely loyal during its period of service" is reasonable, however.
2. "The second type of bond allows an antipaladin to gain the service of a fiendish servant." The fluff is what you want it to be, but since you're asking on the rules thread, it says that the boon is the service of a servant. The spell part of it is just how you claim that reward.
3. Again, rules thread, so the answer is no, you can't summon devils. You can't serve devils. If you serve devils, you will lose all of your class features and just be a feat-less fighter with bad body odor. (Devils are LE, and Antipaladins are CE. As an Antipaladin, you have to be serving something within one step of CE.) That said, LE Antipaladin is probably the most common homebrew for the class. Even so, no, you can't summon something from the other side of the Law/Chaos spectrum. If the options are too limiting, consider asking your GM about the expanded list provided by Summon Evil Monster. That will fill in a lot of gaps.
4. You can touch it, it can hit things, it can pick up things, and so on. Not sure exactly what you mean. Now, it is a little weird- you're still subject to the restrictions of a Summon spell (your new friend can't summon anything or teleport), but there's mention of "dying"- normally that's just for calling spells. So GM interpretation on that one.
