Backpacking round Europe - Group Travel

I'm 18 and I want to go on my first travelling experience backpacking round Europe. I want to go in September cause all my friends are off to uni and as I'm a student I want to stay on a tight budget, so stay in hostels etc.
I want to see as many countries in a month as possible, but im flexible on the countries, but would like to go to france, germany, spain, portugal, italy, sweden, norway and russia in particular.
Looking for some travel partners around my age (18-24) that want to backpack around Europe on a cheap budget, experience the cultures, see a few sights, go pub crawling and partying, try new things and meet new people.
Possible do a few activity like skydiving or bungee jumping along the way as well, just for the thrill!
