YES. YES.
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
Yes it depends on many variables such as what the wire is made of the size of the wire whether the wire is a multi strand wire. What governs the amount of voltage a wire can carry is the insulation that is wrapped around the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation is tested to destruction. The label that is given to the wire insulation as a result of the tests is the highest safest voltages that can be applied to that particular type.
yes but fused wire is safer.
