How do I delete stuff in ZeroEditor?

How do I move command posts?

And finally, how do I make people die if they enter a certain area?

I want 2 know for my Mos Eisley cantina map!

Read the documentation.

How do I see one special spot? I wanna get just the cantina, but it makes me see the whole map!

Use the movement keys. (W,A,S,D, and arrow keys) to maneuver around your map.

question 3:add a deathregion

The docs cover all of this aside from the death region, (which was covered) also check the FAQ topic at the top of this forum since simple questions like that have been answered. Inparticular try the tutorial on how to make your first map. By the end of it you'll know how to use Zero.
