Did some research into Sofia the First and apparently the majority of the Disney princesses that appear in that show exist in the EverRealm, though the ones that have real-world locations are set on Earth as some other dimension. If people don't like the idea of Raya and the Last Dragon being set on Earth, then you can have it in the EverRealm, I guess, it doesn't really change the timeline much either way.
This is all word of god, which I usually take as absolute, though Disney were very against Sofia the First implying a shared universe and even refused to allow the creator's map of the EverRealm showing all the kingdoms to be released to the public, so in terms of this timeline I think it's safe to say Sofia the First is on Earth, and the EverRealm is a region of kingdoms, and Sofia's amulet can summon princesses from both the past and the future, which is somewhat implied though only explicitly stated for the past.
Yes, I am unironically analysing the worldbuilding of Sofia the First, of all things...
(also side-note but I'm gonna add the Tinkerbell movies to the rough timeline, then the only other things I'll add to that will probably be Zootropolis and Chicken Little if I can find good places to put them, though with the way expanded Ducktales/Mickey media handles human/animal coexistence I can probably just find dates in those movies then put them there relative to the human world)
