Let me preface in that i've only kept up a bit with the games since Help wanted came out, and didn't know much from the books outside of the trilogy (so i don't know much in the realms of fazbear frights. So i don't know if any of these have had more information come along or hints at them.

In FFPS, Is Henry still 'alive' or is he possessing something? The line "Make myself sleep" sounds as though he could shut himself down anytime, or is he just referencing killing himself?

What is the significance of the "12-6" AM times the games all usually take place during? What about nighttime specifically causes the animatronics to become more "active"? is it just a classic horror trope of "At night, the spirits come alive" or is there a lore reason?

Is the true reason the night guard in the first two games is in danger that, like baby was programmed to kidnap/kill when she saw only one child, the animatronics see the nightguard and attempt to kidnap/kill them by stuffing them into a suit because they are the only one there? I know the explanation that phone-guy gives, but it's pretty clear he knows next to nothing himself.
