1) What are those?
2) snatch, clean, press, pull-ups. test technical lifts before basic strength lifts.
3) you can test your BS, but keep in mind it may be tainted somewhat becuase of all the other work, namely the cleans (how affected it is depends on a few things, such as how close your max clean is to your squat).
4) Max is your absolute maximal effort. Sorta max is really a product of being short on training experience--but at that moment, it's still your max effort. You should not be holding back. Don't be afraid to faii on an attempt.
5) Oh wait there is no 5.
