What is the ruling on withdrawing money from a credit card belonging to a friend accused in a case and sending it to his family, knowing that the friend is indebted to banks and may not repay these debts?

It is not permissible to borrow using an interest-bearing credit card or to deal with usurious banks. Giving false testimony is also not permissible. If one wishes to borrow without interest and their intention is to fulfill obligations rather than to withdraw funds deceitfully, then there is no objection if the borrowing is from Islamic banks. However, if it can only be done through usury, then it is forbidden.
