They look very normal to me. But if by normal you mean having the typey look with the short muzzle and 90 degree stop, they may not be absolutely perfect. It's very hard to tell at those angles, however. The one on the right looks like he or she won't have as much of a defined stop, but the one facing frontwards looks to have a pretty nice stop.
I agree with Stella and Ashley, I would ask to see pictures of the parents and their previous litters if they have any. You can judge what the puppies will look like based off of those. Also ask if they have pictures of the two puppies in profile views.
