Girlfriends Mom Jailed For Domestic Abuse

My girlfriend (19f) has a protection order against her mother in place after she was arrested on friday for domestic violence. Since then, her father has been trying to get her to revoke her statement for her mothers sake and has been harassing her for two days straight. is this a violation of the protection order? also her mothers boyfriend came over today and entered using the door code, installed a camera, and took groceries out of the fridge for her mother. is this legal? Is she legally able to change the door code until the order is up, so that man cant come inside?
