And besides that, they still have plenty of living characters we know they want to do as well (Lily, Arthur, Gwen, Lancelot, Merida, Dorothy, etc.). And who knows what other suprises they have in store for 5B, as they are only a few episodes in with filming them. Overall, there are alot of characters they are trying to juggle. Hopefully, they can manage it. Honestly, OUaT may have bitten off more than they can chew.

Being in the Underworld, make it is obvious that some dead characters would be returning, for small appearances. It is a form of world building, and the show needs to remind the audience that not only Hook is trapped down there. Dorothy will probably only be in one episode, to reintroduce Zelena back into the storyline. The rest of the characters you mention will probably get their closure, once everyone returns to Storybrooke.

So far we know:

5.12: Premiere and possibly Regina-centric

5.13: Snow White-centric

5.14: Rumplestiltskin-centric

5.15: possibily Zelena-centric
