Explanation:

Fredbear's is pretty much generally accepted the be the first location to open. I believe not only is it the first but it also stays open for longer then we think, and probably closes sometime before the withered location closes. Fredbears is the origin of the Golden animatronics with purple accessories, and these two animatronics are only in this location. Next it gets a bit iffy but I believe Circus Baby's likely opens right before FNAF 4's gameplay. Simply because CC is fucking terrified of what he saw. What did he see? Elizabeth getting scooped. After Circus Baby's closes i could see the first FFP opening shortly after (sometime after FNAF 4). The first FFP is the withered location, the FNAF 3 phone calls location, the location of the MCI / Charlie's murder. This location also contains two golden suits, however they both have black accessories. This Fredbear would later be possessed by Cassidy, while this Spring Bonnie would later become Springtrap. The Springlock incidents that occur in Fredbear's cause the Springlocks to be retired at FFP and FFD likely causing FFP to decline. ALSO: The Springbonnie suit is likely sealed away in the first FFP. The FNAF 2 location is pretty self explanatory, simply put William returns, uses the G. Freddy suit to kill five more kids and then fucks off to avoid being arrested. Sister location could occur inbetween FNAF 1/2 but I don't think so based on the V. Hard cutscene. FNAF 1 occurs, William fucking destroys the bots, gets Springlocked. And then I think SL occurs afterwards, FNAF 3 occurs, and then FFPS. . . phew.
