Basically, put the food and water at the end of the cage. Mom will get up when she wants to. You do not want to give the mother rabbit a reason to kill its young and it will do just that if you start handling them.
Right now mom is not that hungry.
I had rabbits so I know about Mom doing the kill off. Not by walking on them but by biting the young on the back of the neck. Nothing you could have done about it so leave them. After all rabbits are doing wonderfully good in the wild.
Whatever you normally feed your rabbit is probably fine; Rabbit Chow, or whatever.
yes it can
The mother rabbit will produce milk to feed her babies and if you watch would will be able to identify which female they are sucking on.
they can't have babies without a male.
they have to feed their babies
Yes, all you will need is male rabbit
Yes, The father rabbit plays no role in raising babies. The mother and babies are on their own.
Female mammals feed their babies milk from their bodies. http://www.encyclopedia.com/doc/1G1-186991287.html
You can't. The female needs the male to mate with her if not she won't have babies.
