What does it mean when a cars engine has no compression I was looking on craigslist for a car and I found one but the guy that is selling it said that the engine has no compression.?

do you seriously think that theres a hole in the piston in all the cylinders? or the rings are gone in all the cylinders.. highly unlikely.. the main cause of loss of compression is the rings are burnt gone. the rings are stuck, the valves are stuck, hole in the piston and/or head, bent valves, or the timing chain/belt came off, or broke. with all the cylinders being down, i'd look into the last one. that's the only thing that would be logical to effect all the cylinders evenly.

If the timing belt broke in a 1994 Mazda protege 1.8 sohc do the pistons hit the valves?

They can. The only way to know for certain is to put a new belt on and run a compression test. If one or more cylinders don't build compression after you've properly installed a new timing belt, the piston kissed a valve. BTW, it doesn't take much to bend a valve beyond being usable.
