When two objects are moving with respect to each other at different speeds, and that difference is a good fraction of the speed of light, then the rate of time passing on one object would seem to an observer on the other object to be different.
Time
The noun 'speed' is an abstract noun as a word for a quick passage of time (time is a concept).The noun 'speed' is a concrete noun as a word for the rate at which someone or something moves; a word for a physical action that can be seen or measured.
If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
Mach speed has nothing to do with passing out. A pilot might pass out from high acceleration, but this has nothing to do with speed.
Distance and time are the two factors that speed depends on. The definition of Speed is change in Distance per change in time. S=D/t.
Time
That would depend on your speed relative to the mirror. If you were holding it in front of you, yes. If it was stationary and you were passing it, no.
That will obviously depend on the speed.
That would also depend on the distance. Use the formula distance = speed x time. Solving for time: time = distance / speed.That would also depend on the distance. Use the formula distance = speed x time. Solving for time: time = distance / speed.That would also depend on the distance. Use the formula distance = speed x time. Solving for time: time = distance / speed.That would also depend on the distance. Use the formula distance = speed x time. Solving for time: time = distance / speed.
Time and distance
That will obviously depend on the speed.

Common sense, decency.. that sort of thing. Legally... how it's categorised would depend on the state, but most would consider speeding up to prevent someone from passing to be aggressive driving.

You don't convert hours to km. Hours is a measure of time, km. is a measure of length.If you mean, how long would such a trip take, that would depend on the speed. Use the relationship: distance = speed x time. Solving for time: time = distance / speed. If distance is in km. and speed in km/hour, then the time will of course be in hours.You don't convert hours to km.
