in fnaf4 there is a kid that looks a lot like balloon boy he probably is BB, the Freddy bully appears (maskless) on night 3/4 (I don't remember) so we can assume that he is toy Freddy, the toy girl looks a lot like Susie and the toy that's different from the rest is toy Chica so she is probably toy Chica, the plushtrap kid just seems like a male plus he was holding a BONNIE plush so he is prob toy bonnie, the pigtail girl would be mangle because that's the only one left, if you want to go deeper though pigtal girl looks like circus baby and CB's band is the funtimes and funtime foxy (fnaf SL) looks like funtime foxy (fnaf2).
