Hi and Welcome to YT!
Oh my! Sounds like you have your hands full!
Basically, young pups should be confined to one room, and not allowed the run of the house until they are potty trained. Teach them to potty on a pee pad or newspapers, reward them with tremendous praise AND a treat when you catch them in the act of using the pad.

As for sleeping in the bed... I think most end up there, lol! I think you may have a hard time switching them back now...
