1.if i have 2 weapons each with 50% crushing blow, and i use frenzy, does that mean i have 100% crushing blow each time i swing?
2.same senario, but i use concentrate?
3.same senario, but i use frenzy first, then during the frenzy state, i use concentrate.

4.can i have more than one warcry active at one time? for example, can i use shout, then battle orders, then battle command, then battle cry? Will all the warcries be active at the same time?

5.Does battle cry work on act bosses or superuniques? If so, is there a penalty?

4: Yes. Shout, Battle Command, and Battle Orders will all be active on you (and anyone in your party you cast it on) at the same time. Battle Cry affects monsters where the other 3 affect you and your party/hirelings, but yes you can have it active on a monster while the other 3 are active on you.

5: It does work, I'm unsure of whether there is a penalty or not, but I don't think there is.

6: I do know that it works at full strength in PvP. When my singing Barb uses it on another player, his defense goes in the negative- doesn't matter how high his defense is, it could be 100k and it goes negative.
Also, there is a general PvP penalty which results in doing 1/6 damage, the only exceptions to this that I'm aware of being Thorns and Iron Maiden. The three you mentioned are not penalized, though as I said your overall damage will be.

1.-3.: No, crushing blow on weapons (as well as critical strike, open wounds etc.) only work for hits with the particular weapon.
