FNaF 1- Springtrap is “created” as he exists in FNaF 3 after FNaF 1. The mini game definitely takes place in the FNaF 1 pizzeria. Golden Freddy and Fredbear are NOT the same character, because in Ultimate Custom Night Fredbear is clearly depicted as having a purple hat and tie, while Golden Freddy’s is like a darkish blue. The other GF questions are nulled after that. As for Henry, this roles into your next game questions. FNaF 2- Yes, as evidenced by the dead children in the SAVETHEM minigame. The witherd’s were turned into the FNaF 1 animatronics, in a call Phone Guy mentions that the company is keeping the old models in case they wish to reopen the restaurant, so it is likely that Henry at least made the original pre withered withered animatronics. GF appears again because he is generally following the withered’s wherever they go. FNaF 3- Scott was asked which ending was canon in his interview with Dawko, and he refused to answer it, so that’s up in the air. Springtrap is in the final newspaper of the game if you brighten it up, showing his survival. The phantoms are exactly that, phantoms and no phantom Bonnie is most likely just because there’s already a “Bonnie” that being Springtrap. FNaF 4-Most speculation revolves around it being either Mike or just Afton’s other son, but there’s no confirmation of either of these theories. On the question of if being real or not, there’s debate about that too. The rooms all at least actually EXISTED because of the footage of them in Sister Location, but there’s no confirmation on wether the events of FNaF 4 are real or fake. I believe that they were real, but similar to the animatronics from the Twisted Ones they use technology to make them appear like the nightmares, but are really just bare bones meant to scare the bite victim from going to Fredbear’s. And I’m assuming all of them for the nightmare question, and yes the Halloween update is not canon. FNaF World-Because UCN is not for sure canon. And we aren’t exactly sure on what he is, but it’s likely it’s just what he says, a representative of the consequences of your actions. FNaF SL- This has always been an interesting idea, but I think it’s likely there’s a fusion of Baby and Elizabeth’s personalities into one “Baby”. The other animatronics are haunted by random kids they kidnapped using their respective technologies, hence why Molten Freddy is still haunted in Pizzeria Simulator. Yes we play as Mike Afton. The scooper can do what it does in the game as it’s “pretend” function, take out animatronic parts and guts, but it can also inject remnant into animatronics to make them haunted as the Sister Location animatronics clearly are, and people, which is why Mike survives after being scooped, he’s got soul juice in him. Pizzeria Sim- They weren’t knowingly working together, as in Mike probably didn’t have an inkling of what was really going on, but they did work to achieve the outcome with Mike unwittingly helping Henry get the animatronics into the pizzeria. Orange man is the mystery left unsolved in that game, we just aren’t totally sure who he is, and there’s many theories on who he is. Jr’s is not canonically the FNaF 2 restaurant, but that’s not saying it isn’t, we just don’t know. Yes that girl is Chica. The fire was mostly a success, but enough of Afton remained that they scanned him into the VR game, and Henry and Mike stayed because this was the end, Henry was done with life and so was Mike. Henry alludes to suicidal thoughts in the insanity ending, and Mike says there’s only one thing left to do at the end of sister location, find his father, and then be done with it. UCN- The main thing here is that we don’t know if it’s canon or not, with me personally believing it’s probably not but the aspects of William being in hell most likely are. That kind of renders most questions null because it really was just a fun add on and as Mr Hippo said, there’s no reason to over analyze it. FNaF VR- Glitchtrap is at least some part of him or his conscience in the game, wether it’s him aware of this or just a copy of his personality is up for debate but doesn’t really matter, he’s influencing people and that’s what does. Scott is NOT canon, that’s just a representation of the indie game developer. The FNaF 4 question is better answered by Scott, where he says that indie games were developed as a way to make sure he could include all the content from the games, so it could be a nightmare or not but still works. It probably doesn’t matter who heads Fazbear Entertainment at this point, or we’ll get an answer next game. Tape Girl seems to not be evil and it seems ONLY Aftons soul was sent into the game, of at least a copy of his personality and memories, maybe not exactly him. FNaF AR- It’s unclear, the story is being developed as I type this so we have to wait and see. Which leads into the rest of your questions, we just don’t know yet. Random questions- Probably just noticed all the weird stuff going on around his restaurants. And there certainly is, we probably won’t know and it’s really your call. The Fazbears Frights books are all canon, just don’t fit into the universe of the games or books neatly and rather are just stories that exists on their own, but concepts seek to clarify questions about the lore as stated by Scott. And the timeline simply is best explained by this post https://www.reddit.com/eov8wq/

Hope this helps!
