The pictures were taken before the first Terminator movie was filmed. These are test Polaroid pictures of Linda Hamilton as Sarah Conner.
One of the pictures has documentation on the back explaining the part that Sarah plays in the movie.
In the set of Arnold pictures, the top one is a stunt man showing how Arnold will break through the windshield of the car. The bottom two are pictures of Arnold holding a gun.
