Is it legal to pay acredit card with another credit card I dont mean to transfer balance from one card to another what I mean is to pay a credit card with another by buying a gift crd to pay other.?

This can be done, but is usually done through the use of a "convenience check" that credit card companies send out in the mail. They work like cash advances on the credit card.

The problem is if you are borrowing money to pay for money you borrowed, you are headed for disaster fast. You're robbing Peter to pay Paul, which will end in financial disaster for you, when Peter and Paul quit giving credit and want their money back.

You'll probably borrow the money at a higher interest rate (cash advances are always the higher rate), to pay for the money that you borrowed at an already moderate to high interest rate. Don't dig a bigger hole than the one you might already be in. Cut them all up and then pay them off as quickly as possible.
