You have not answered the question. Are you allowed to fly the aircraft totally ALONE? It would seem not, even though you have the licence.
If your friend has to be there with you it is for a reason....probably because he is involved with the group.
As there can only be one PiC then that would obviously be him.
As I said before you have your answer!
