A cage, bedding, running wheel, water bottle, food.
Dwarf hamsters - each other and on suitable hamster bedding. Syrian - on their own and on suitable hamster bedding.
They will make a nest out of the bedding you put in the cage.
Shredded newspaper is fine to use for bedding for any hamster, but if you think you hamster is slightly uncomfortable you can always add some real hamster bedding, it will save you money. :)
When you clean your dwarf hamsters cage you should put fresh bedding in because they could have stored food in it that could rot or they might have urinated in it which should be cleaned so change its nest whenever you clean its cage which should be a around once a week.
It means it is getting used to it new home.
You should put your hamster in a safe place, or have someone else hold it for you. If you have a hamster ball, let your hamster exercise in that while cleaning out it's bedding.
If your hamster bedding looks brown it needs to be changed. Urine turns the bedding brown. It should be changed weekly.

No, you should separate them.
He is making a nest for himself to sleep in. All hamsters do that. I have had two of them.
