Yes. They should get along fine.
No, No, No, triple No. Every rabbit needs it's own space after they reach sexual maturity ( 6 months), they are very territorial. They may get along fine for a short while and then one morning you will check and one or all 3 will be beat up on. They will have slit ears and fur missing and may have bloody scratches on their bellies. It is a triple threat not worth the risk if you love your bunnies.
