um, in order:
1) the food already there will only last all of us a week or two, true. but my school has a small greenhouse, i just learned not four days ago, but that wont last us too long either. sense it's an inner city school, we have a wal mart just down the road, so we'll be some of the first to raid it.
2)true also. the makeshift blades part was just for fun. we gotta occupy our minds with something. and our library may only last some of the group an few months.
3)we've planned for that too. there is an internal courtyard type area with plenty of rocks and a few trees. i'll see if anyone of us knows how to fletch an arrow from scratch.
4)i dont think i know it, if a few searches come up emptyhanded: we've still got the 2nd and 3rd floors to fall back to.
5)i see what your saying but if it were a simple geometric shape it may be taken as another person's/group's tag. so i took something that a large enough population (around here at least) knows its relation to safety or a friend.
