I wouldn't recommend it because they could get hurt and it may be to cold or to hot......they like room temperature
Hamsters can both jump and walk.
Yes
They should start hobbling around a few days after birth. For them to fully walk, it could take anywhere from 1-2 weeks, maybe later. This was how it was for both of my 2 golden hamsters they gave birth. Be sure not to disturb the mother and clean the cage before she gives birth. It is safe to touch the babies after 5 weeks.
Pet stores and friends could take baby hamsters.
Nothing. You might need to take it to the vet, but I'm sure it would still be able to walk if it rests for a bit.
They run on hamster wheels, but if you don't have that it's also good to take them on a walk.(you should make or buy a right sized collar.

Usually hamsters have two toilets. One for the feces and one for the urination. It's usually in a private corner of the cage or sometimes next to the water bottle.
Sunset, in the wild hamsters usually come out at night.
They love to walk or run for that matter in their hamster wheel they LOVE ITTT!!!
Hamsters don't get pregnant. They lay eggs. If your hamster has increased in size in a rapid period of time, you should probably see your local vet.
Take it to the vet.
