I mean you can. But they might stop you at check out because you dont match the cards picture on the back. My friend tried to use her dads and she got in okay but at checkout they wouldn't let her pay. It was a hassle to get them to accept it
No you have to have your own card however if she has one the second card is free of charge.
Also, if she's the only one on the card, you can get your name added.
Sure!
