It all depends on the location and circuit ampacity. Kitchens usually only have 2 or 3. Garages can have anywhere from 1 to 14. Dining room circuits can only have outlets on them that serve the dining room. Clothes washing machines, air conditioners, and other appliances get their own circuits. Throughout the house, such as bedrooms, hallways, living rooms, ets, generally don't go over 14.
No, the electrical insulation rating of a 15 amp duplex receptacle is only rated at 130 volts. The 15 amp 240 volt receptacle is rated at 250 volts. The 240 volt receptacle also has a tandem pin configuration instead of the parallel configuration of the 120 volt device. The different pin configuration is so that a 120 volt electrical device can not be plugged into a 240 voltage receptacle.
Yes
Eight on a 15 amp circuit, tweleve on a 20 amp circuit, including the gfci receptacle itself.
Yes, the rating on the receptacle is the maximum amount of voltage that is legally allowed to be applied to the device.
120 va on a 120 v socket means you can draw up to 1 amp from the socket. The number of outlets/sockets depends on the amp rating of the circuit. If it's 10 amps you can definitely have ten sockets and your local wiring regulations might allow more, on the basis that they won't all be used at once.
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.

If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.
Most residential service in USA has both. In the USA 110 to 120 volts is a given and it would be very unusual not to have 220 to 240 volts. It can be easily tested at main panel with a volt meter. Or as an alternative call your power company.
If it is a 120/240V receptacle (such as for a dryer), then yes, there are two 120 volt leads and a neutral in the 240 circuit, the adapter is just using one 120 volt lead and the neutral to convert it to a 120 volt circuit.If the circuit is just 240V, then there is no neutral.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Yes, the voltage listed on the bulb is the nominal voltage and it will work perfectly on a 120 volt circuit.
No, not a good idea. You have to use a 347 volt ballast.
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.
