It may be important to note that later that night they tried to trick the same high girl into giving them both head, to which I removed her from the situation and made sure she got back to her tent safely

Your friends are rapists in training, at best. 

If you feel they are salvageable, you might tell them, "That would have been rape" and see if you can make them understand. Preferably singly as they'll egg each other on in a pack. 

It goes against the grain with me to say "well done for not raping or enabling rape", but well done for standing up against the group and holding to your principles. Keep doing that and maybe warn the girl, or any other girls who hang out with these jerks.
