That's a russian campbells dwarf hamster. If you google that name you may see more which look like your daughters ham. Although chances are high that they're hyrbrids, unless they got them from a breeder.
What are their names? You never mentioned.
You're in a great place to get plenty of help, and your daughter can probably learn a lot from here to if she wants to do a bit of research into looking after her new pets.
