1 - Carl and Ellie's Adventure Book from Up
2 - Hercules' Zeus pendant from Hercules
3 - Pocahontas' necklace from Pocahontas
4 - I concur with
@LittleBird - I believe it to be Fa Zhou's helmet from Mulan (or the helmet Shang gets from his father, though the feathers don't quite match on top). Either way, most likely something from Mulan.
5 - This is the only one I'm not sure of since I can't think of a movie where a train was the family heirloom. There's a train in Ant-Man, but it's very obviously Thomas the Train Engine where this pin is not. It might be the Disneyland/Walt Disney World Railroad train, since trains were so important to Walt?
