If it is an oil lubricated compressor (which most vertical/uprights are, only a few are oil-free). Not only can it NOT be used horizontally, it cannot be transported horizonatally with oil in the crankcase. Oil will seep out of the crankcase, past piston ring, and into the pump causing hyraulic lock.
Generally not. It depends on the particular design. Ask the manufacturer.
Yes, you can transport a water heater while it is laying down, but it is recommended to keep it upright to prevent damage to the internal components. Transporting it upright reduces the risk of leaks and ensures the water heater functions properly.
typically, a refrigerator should be transported upright, however, in the event that it has been laid on its side for transport, leaving it upright for a period of 24 hours without running will typically allow it to be used with no ill effect. However, if the refrigerator has been plugged in and the compressor has been run "dry" it may not be salvageable.

"Laying down" is used when you are placing something down, while "lying down" refers to the act of reclining or resting in a horizontal position yourself. So, you lay an object down, but you lie down yourself.
