3. I have a cinterblock wall that is framed with 2x4 sole and head
plates and 2x3 studs so there is an inch of space between the
cinterblocks and the studes. Is it OK for a wire to run behind the
studs?

Yes, but they still have to be stapled

Why would they need to be stapled? Seems to me that falls under the clause
permitting NM to be fished through voids in existing walls, doesn't it?
