You can use Pass Index to drive some values of material nodes (in my simple example first Suzanne has index 0, while second has index 1, but you can build some more complicated trees).

A (known) multiple images version:

For unknown number of textures (like an image sequence) you should ask a specific question about how to "read" (and maybe use as new driver) the Object Info value inside the material node tree and/or how to manipulate the offset of the Image sequence texture node from inside the material node tree: I didn't find a way yet.
