If a creature is turned into a copy of Ashcloud Phoenix, what happens when it dies? If it does return to the field, will it still be a morphed Ashcloud Phoenix, or will it be impossible to flip?

When a nontoken creature dies as a copy of Ashcloud Phoenix, its death trigger will trigger and it will be returned to the battlefield face down when the trigger resolves.

It’s no longer a copy of Ashcloud Phoenix, however, and won’t be able to be turned face up unless it has its own Morph ability.

If my oppoment casts rally the ancestors, and puts 4 Jaces on the field and they control a Zulaport Cutthroat, does 3 of the jaces being placed in the graveyard trigger Zulaport's ability?

Yes.

When a creature moves from the battlefield to its owner’s graveyard, it dies.
