1 : 5 or 3 man,but 2 in popcap.

 

2  : and sometimes when u build towers ,and ur hero or units just trapped there .

 

3  : control attack should exist.

1: You can sell units (not while in battle though) by right clicking on their image and choosing "sell".  The only problem I have with this here is the fact that you can't sell more than 1 at a time.  If someone knows how, please post it.

 

2:  This is a problem that you can have in any game.  The units that can capture build pads don't have to be right on top of it, they can be a bit away, so don't stand them right on top of it when you build it.

 

3:  Control Attack does exist... hold down Ctrl and right click on the ground where you want your units to move-attack to.

Control Attack, I think he ment it in C&C terms. By holding down control you could attack your own units to kill them...
