Possibly. You will for sure destroy the engine. too much oil is just as bad as too little. The crankshaft will make contact with the oil and create a situation where air is mixed with the oil. This mixture will have poor lubricating properties thus causing severe engine wear.
YES
Get the air out first..
replace the oil pump or the engine could blow
Depends on the oil capacity of the pump itself.
No. The damaged may have occured before the new pump was installed.
Yes, both are possible, you need to check oil pressure with a mechanical gauge. If pressure is over 80 psi then the oil pump is bad.
you should never rev your engine when you start your car it sometimes takes the oil pump time to pump oil up into the engine heads if you rev it too much your engine could suck a valve or blow a lifter.
Remove oil from pan or go for an oil change. Too much oil can blow out the gaskets.
your problem is your oil pump.it has a blow by ball and spring to release excess pressure and it is stuck closed. replace oil pump !
You could blow the gaskets

Adding 5 quarts of oil to an engine and overfilling it can cause the seals to blow out. This can cause engine failure.
