What happens if you turn crankshaft counterclockwise?

It should be okay as long as your timing belt is still attached. It is unlikely that an engine will be damaged by reversing, as the oil pump and possibly the water pump are the only things it can do. It would be a bit of a challenge, but four revolutions shouldn't hurt it at all.

Can you drive without crankshaft pulley?

If it was the crank pulley, such could fall off (eventually) and if it does cause a fair amount of damage if it happens while the engine is running. Indeed, if it's the crank pulley and the harmonic balancer comes off with it and the engine continues to run that can damage the crankshaft. That would be very bad.
