polymorph and apply subtype ability question

[Wintercome]

If human druid change her form beast by wild shape, now she is Animal Type for ranger's favored enemy ability?

or Is she still Humanoid(human)? or Is she Humanoid(human) AND Animal?

How about demon changing form through other polymorph effect to human, element, or other thing? Does it still apply paladin's Smite evil?

Finally, If demon possess other creature, that possessed creature can be target smite evil ability?

[Starglim]

The druid is still a humanoid (human) and not an animal.

The transformed demon is still an outsider (chaotic, demon, evil, extraplanar) and not a humanoid, outsider (elemental) or what have you. A paladin's smite affects it as an evil outsider.

Not sure about a possessed creature.
