There is no problem with that voltage. As long as the voltage is plus or minus 5% of the nominal voltage of 115 volts it is considered to be in the 120 volt range.
Because it is a 220 volt outlet instead of a 120 volt outlet. Now, if this is a standard 120 volt outlet that is reading 209 volts then someone has made a mistake in the wiring. You need to call an electrician to straighten this out.
A power supply receives 120 volts of AC power from a wall outlet and converts it to 3.3, 5, and 12 volts of DC power.
Yes- 120 volts is just the label given to it for ease of the consumer. The voltage actually fluctuates several times every second, and can reach as high as 175.
In the US a general purpose receptacle outlet would be 120 volts; England 240 volts, France 115 volts, Libya 127 volts, Okinawa 100 volts, Tanzania 230 volts . . .; all depends on where your house is.
Either the supply or the multimeter is faulty.

Yes - a hair-dryer rated at 120 volts will work in a 110 volt outlet.

Yes you can safely do this. Most appliances that are marked 115 volts will operate on outlet between 110 and 120 volts safely.
America 120 volts 60 Hertz, Australia 240 volts 50 Hertz.
Either the supply or the multimeter is faulty.
No. It would have to be wired for 220 volts and would have to be rated for 220 volts and would have a different configuration so that a typical 120 v plug wouldn't fit the outlet.
Someone has wired 240 volts into your 120 volt outlet. If you have 240 volts you need a specially configured outlet so that a standard 120 volt plug cannot be inserted. If you have this situation you would see 120 volts to ground and not neutral. Sometimes if you don't look carefully an outlet will look like the standard 120 volt variety but it isn't. One of the slots is horizontal and not vertical although there may be a small vertical split. 240 volts doesn't just magically appear. What you are describing is on purpose. If it really is 120 volt receptacle you need an electrician to put in the proper receptacle or re-wire the circuit.
I have never seen a 100 Volt rated outlet. Usually outlets would be rated for 110 to 120 volts for residential use, or maybe 150 volts. The rating is separate from what voltage the outlet is providing. If your outlet is supplying 100 volts, as measured by an accurate voltmeter, you have some problem in your wiring or a faulty outlet. If there is only 100 volts at the outlet get an electrician to diagnose the problem if you are not completely familiar with home wiring. In general you should never use an outlet that has a voltage or current rating less that the device will consume.
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
