Put fun things like wooden chew toys, paper towl cores, small plasic balls (large enough that piggie can't fit it in their mounths), toys with a treat in the middle, and other things for them to climb on. Switch the toys around once every week or so to keep the cage intresting. You shouldn't rearrange the cage too much or you might confuse you pig. Also, try putting something with a bell or rattle in it. My two babies love those kinds of toys!
Depends on the Guinea Pig - also on the cage. I keep my guinea pigs in an open-bottomed cage.

Yes the minimum for two guinea pigs is 7.5 feet so that's a good cage.
Most likely because they may not like their cage or was enjoying what they were doing... unless you can get in a guinea pigs mind no one really knows why.
They are supposed to go to the bathroom in the bedding in their cage.
