What needs to be checked is the voltage of the low voltage line. If it is 120 v, that is suitable for a 120 v LED fitting. Second, is the line capable of carrying the current needed by the fixture. The answer to that is, probably, but it still needs checking.
need a universal voltage ballast 120/277 volt or a 277volt ballast
No, by reducing the input voltage by half the output voltage will also be reduced and will not have enough voltage to operate the fixture it is connected to.
Is it incandescent or flourescent? If it's incandescent it will work okay--it'll be dim but it will work. A fluorescent probably wouldn't fire. Now having said that, if this is a European lamp google "110v European base bulbs" and you'll find light bulbs that work on 110v but have bases that screw into European sockets. Just change the plug on the lamp and you're golden.
The metal halide light is a commercial fixture. Wire it to 120 volt. 277 volt is the star point voltage of 3 phase 480 volts. Likewise 347 is the starpoint of 3 phase 600 volt. By wiring it to 240 volts the voltage might not be high enough to ignite the lamp. Try it and see, it won't do any harm to the fixture. Make sure that the wires that are not connected are taped off as there will be voltage on them.
No, a light bulb rated to work in a 120 volt lamp will not work properly in a 12 or 24 volt low volt lighting fixture. I don't believe it will harm the fixture. If you did get a 120 volt light bulb to fit into a low voltage light it would probably just be dim.
If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.

It draws 2.5Amps
No, by reducing the input voltage by half the output voltage will also be reduced and will not have enough voltage to operate the fixture it is connected to.
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
It sounds like the fixture that you acquired was from an industrial site. 277 volts is the star point voltage of a 480 three phase system. You will have to change the ballast out to the proper voltage that you need. If you want to spend some money you can get a step up auto transformer to make the conversion but the cost would off set the cost of a new fixture many times.
No, it will cause the bulb to blow. A 12 volt light is DC voltage and your home outlet is AC voltage.
No, NEC section210.6(A) The voltage shall not exceed 120 volts nominal between conductors that supply luminaires(light fixture) in dwelling units. Read the code section for full details.
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
