Questions About Possible Sexual Assault And What Can I Do?

Hello! I am a 15 years old boy, when I was 12 I was a victim to many possible sexual assault crimes and I just want to share my experience, learn if these situations were crimes and learn what I can do next. For privacy purposes I will be referring everyone involved in these situations as random names these are not their real names.

Situation:
For school, I had to go to go to this school camp where we were able to participate in many outdoor activities and we stayed in hotel rooms when sleeping.

What I think Bob did wrong:
1. Bob threatened to rape and molest me before heading to the school camp quote "Watch out, I am going to rape you." (He never did)

1. Bob grabbed my groin area without my consent while I was climbing down the bunk bed.

What I think James did wrong
1. When I was going to the shower in the shared shower in our room I was getting in and I told everyone that I was going to head to the shower. I took off all my clothes in the shower room and was about to lock the door until James opened the door and took a picture of me naked then posted it on snapchat.

1. When I was sleeping while only wearing my underwear, James (who was also only wearing his underwear) went into my bed then started touching my chest area and tried asking if I wanted to participate in sexual intercourse.

2. While heading to the bathroom at night James squeezed my chest while I was washing my hands after going to the toilet (It was dark I did not see him)

3. James pulled down my underwear and pinned me onto the bed while telling everyone else in the shared room making fun of my genital size.

Note that James and Bob was both 14 at the time and I was 12 at the time. I already talked with the school about this and they kept saying they are going to look into this but this sexual harassment has still been ongoing.
