I would not keep that many cards in my name. Your first mortgage app or large car loan could be in limbo because of too many cards. You would have the potential of running all those cards up in the eyes of the lender.
One or two cards, with consistent on time payments is what you want.
You will have to contact each card issuer and explain that you no longer have the card in your possession and wish to cancel it. The downside is they are of course going to try to convince you to keep the account open.
