Are we talking UNNEUTERED male cats, and UNNEUTERED male rabbit? You are leaving yourself open for a lot of spraying. Neutered males should be able to co-exist unless someone has a dominant intimidating personality, which can't be determined until they are all in the house together.
The male rabbit should never be housed with the female rabbit. He should never be introduced to her habitat. To breed she should be taken to his cage and removed after they are done breeding. The male rabbit should NOT be exposed to the kits.
Male

If you want babies, Yes.
Rabbits are no more harmful to human beings than cats are PLUS rabbits do not carry any diseases that can be transferred to humans. If done in time, just like with cats, neutering will prevent a male rabbit from spraying. However, just like cats, if a male rabbit has started spraying having him neutered will stop the spraying in 50% of the cases.

The name for rabbit is 'lapin' (masc.) in French. That goes for the male rabbit, or for any rabbit regardless of its gender. 'Un lapin male' can be used if you want to state that a particular rabbit is a male one. A female rabbit is 'une lapine'.
