Is worth i sale all my bikes and i buy one newer bike? and what is your opinions carbon fiber aluminum or steel?
If the bikes don't fit, I'd sell them and buy one that really suited you. Oversized bikes will lead to discomfort and probably less riding (riding in pain is no fun.)
Also, as Doctor Morbius notes, upgrading old bikes can cost more for less return than buying a good used bike that already has the good stuff. By the time you fixed up all your old bikes, you'd have spent a lot of money and would be stuck with a bunch of old, heavy bikes that didn't fit you.
Sell whatever you don't ride and buy something you will ride.
