I wanted to keep one small credit card and pay them off so I had a credit card still, can I keep one or do I have to include them all
The idea is that the unsecured creditors all get treated alike in a bankruptcy. So you have to include ALL your debts in your bankruptcy filing.

You have to list all of your debts when you file bankruptcy, whether you want to pay it or not. Keep in mind, credit card companies check your credit periodically and will cancel a card if you are in bankruptcy, whether you listed them or not. This is in addition to the fact that you are required to list all your debts and you sign your bankruptcy documents stating under penalty of perjury that they are accurate.
