Repositioning a Hand

I have a picture in which there are a few people. One girl has her hands in a different position than the rest of the girls in the picture. I was wondering if there was a way for me to reposition the hand so it is matching to that of the other girls. If anyone would know how, let me know and I will post the picture.

You can try the puppet warp tool

Do you have another picture that you can use the hands from? Or maybe you can take one of the other girls hands? Can you post the picture?
