Hmm . . . I thought the dwarfs were all pretty similar. You may be able to keep them together if there are 3 or less, but the question is why you are getting so many?
With only one male and female, you will have litter upon litter. This may seem manageable to you, even if you have a pet store who will take the babies, but ultimately, it isn't that good for the animals.
Although ours were very cute, with the "teen" babies "babysitting" the new liters it ends up being too much for the hamster, and especially the mother.
In the end, they produced a blind baby/no eyes, and one ended up with 3 legs, and I won't go into all the details.
Sure we loved them, but do you want to do this to your pets? Read a little more about them, and consult with a pet store that actually knows something.
Besides that, the cage/tank will need constant washing, because they all pee and poop and that is very unhealthy for their lungs to breathe in.
