Yes, absolutely. It will not hurt a thing but if the one on bottom goes out, the one on top will not be protecting anything. see this article...

Also you can not exceed the amount of amps the outlet provides. Two surge protectors are okay. Don't listen to all of that crap about how surge protectors are so horrible bla bla bla. None of that means anything. If you tried to plug 100 together that is a different story because the outlet would run out of amps.
It will very likely damage the surge protector
No.
Although a surge protector is certainly not required, it is highly recommended to protect all electronic equipment from damage.
You need to plug in big electrical items, such as a computer, you need to plug it into a surge protector, available at your local electronics store, i.e., Best Buy.
yes
If a surge protector had a very high resistance at all voltages, the wires in the surge protector would short out. It would kick off the protector and make it useless. A new surge protector would need to be purchased.
Reactivation of a surge protector is normally not necessary if your protector has taken a hit. Typically a protector will continue to work without the ned to reactivate it.
I see no reason not to. As long as the surge protector is in good condition and the plugs that are connected to it have a snug fit. Most surge protectors have there own built in protection and if the whole unit is just plugged into the wall outlet the circuit breaker will trip if the surge protector faults.
A surge suppressor or protector is used to protect electronic devices in case of voltage spikes. A surge protector works by limiting the amount of voltage supplied to the plugged in electronic devices by blocking or shorting to ground any voltage above the safe threshold.
A surge protector (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or by shorting to ground any unwanted voltages above a safe threshold. This article primarily discusses specifications and components relevant to the type of protector that diverts (shorts) a voltage spike to ground; however, there is some coverage of other methods
a surge suppressor or protector protects your equipment from spikes on the electrical line.
