It depends on the kind of hamster. Some kinds get along better with others than other hamsters do. My hamster is a Dwarf hamster , they get along good with other hamsters. To be safe , don't keep them in the same cage. Let them smell each other. If they seem like they're okay with each other then put them in the same cage. If you see ANY SIGN of fighting separate them.
no 2 male hamsters will fight, I have a Male Hamster and so does my Brother, we put them next to each other and my Hamster jumped on top of his. if you out 2 male or female hamsters together, they will surely fight
No.
Seperate them and put them in 2 separate cages
yes hamsters require a male to become pregnant.
Male hamsters tend to be less aggressive and protective than female hamsters.
It depends on the type of hamster. Some male hamsters are quite aggressive and have a tendency to kill their young. With that type, the male needs its own cage. Other male hamsters can help raise young, but to be honest, with hamsters even the mothers sometimes kill some of their young, we think in order to ensure the survival of the others. You should read up on hamsters, see if you can find out what type you have, and make sure they have plenty of food. Don't handle the babies too early either. That can sometimes be a problem.
Male hamsters cannot give birth to a baby.

Male hamsters, no matter what type, never give birth. It is biologically impossible.
