I don't see any poison ivy in your photos.
The plant growing on the rock in the third photo is some type of strawberry.
Do any of the other vines have berries on them?

None of them are Ivy, poison or otherwise.
What is the texture of the leaves in the second photo? How big are they? It could be a wild grape.
#3 does kind of look like a strawberry except for the round serrations. Maybe a Potentilla?
