Songs to play live in middle school?

In two weeks me and some friends will play some songs during recess,a
little event,no more than 40-50 min and we are planning to play 7-9
songs but we need some ideas,we are only 3 members,drums,rythm
guitar,lead guitar no vocals or bass,just instrumental.

So far we've got these,we are shure we are playing these:

Seek and Destroy
Sweet child o mine
Back in Black
The day that never comes
One

My friend's got like 3/4 of TTFAF Dragonforce,we might play it but he
messes up alot in the solos.

Any ideas?our "style" is metal but we could play anything
(remember,drums and 2 guitars so no orchest that uses 500
instruments),it doesn't have to be metal
