I'm trying to join the United States Air Force and I would like to know some of the following things?

I have been charged with a misdemeanor of possesion of marijuana, but the court offered me a diversion. I was the designated driver of some friends. I was breathalyzed and blew a zero. I did not consume this substance, but it was left in my car. I'm going to the courthouse to sign this diversion which from what I understand will ultimately expunge this charge from my record if I stay out of trouble for the next year from when I was arrested. Also, I have been charged with battery and assault because I was a bystander at a fight that I did not have any control over. I was a minor at the time of the fight, but I was an adult when I was arrested for possession of marijuana. I was charged with a felony and a misdemeanor. Will these charges affect me when I try to join the airforce? Does me having a Core 40 with Acedemic Honors diploma from high school help these situations?
