The other day you proposed making the timeline, so I started getting information, but I didn't get very far, there are lots of things.
Some notes:
-Everyone keeps saying that "The Lion King could be in any place, even pre-history, since it doesn't show human civilization" but, if you count the Timon and Pumbaa animated series, I think it takes place in release date, since sometimes the characters of that series are shown interacting with human civilization.
-Big Hero 6 is Earth-14123 of the Marvel Multiverse. And probably a different universe from the rest of things, since it is a divergent timeline were the city of San Francisco was remade as San Fransokyo following the 1906 San Francisco Earthquake, while in other places, like in an episode of Lilo and Stitch The Series, is shown that San Francisco is just called the same as in the real world.
-Robin Hood, Chicken Little and Zootopia seem to take place in a world inhabited by anthropomorphic animals instead of humans, so maybe it is an alternate universe too?
-Fantasia, Make Mine Music, Fun and Fancy Free, Melody Time, The Adventures of Ichabod and Mr. Toad and Fantasia 2000 are compilation movies with different segments, some taking place in the Mickey Mouse universe and some even featuring abstract visuals with no plot, so... good luck with that, I guess.
-Hercules 1x44, "Hercules and the Arabian Night" seems to establish that Hercules and Aladdin live in the same era even if Ancient Greece and Middle Ages Arabia are not even in the same millennium in real life.
