Yes, but the cage must be large, and it may depend on the age and gender of the ferrets.
is called a kit same as a rabbit
A ferret will almost certainly kill and eat a guinea pig if it had the chance.
Only if the rat is smaller than the ferret or close to the same size.
A ferret can weigh about 2-4 lbs. A bunny can weigh from 1-5 lbs. It depends on the breed of the ferret and the breed of the rabbit, but it is possible.
I've have put a bird in a ferret cage, but the bars were too far apart and the bird could get out. You would have to make sure the bars are close together and the bird has a perch (I used a small tree branch)
No. Mixing different species is not recommended and you may well end up with a seriously injured or dead hamster. They don't have the same care requirements, and would gain nothing from the interaction.
Lice
No. A Cottontail rabbit is not a rabbit at all. It is a Hare, a cousin to our Domestic rabbits. In-fact if you put a female Hare in a Male rabbits cage, or visa versa they can't breed. They look they same but they are not the same thing.
Carrots or rabbit pellets available at pet stores. Whatever you do, don't keep a rabbit and snake in the same cage.

Yes but u would have to get them at the same age and from the same family of gerbils
Yes, if they are neutered. Some people do this and the animals groom one another.
