if your asking how they figured how many "earth" years does it take for uranus to complete one revolution around the sun--they observe its position in space over a period of time; calculate how far its moved so far, then figure out how long it will take for it to move in a complete circle base on the measurement they took. lol lots of math involved.(takes about 84 earth years BTW)

It's the time it takes for Uranus to complete one orbit around the sun - just like an Earth year is the time it takes the Earth to complete one orbit around the sun.
Since Uranus is much further away, its year is much longer.

Same as any planet. The time it takes to make one revolution around the sun.

The same as all of the other planets. Its the time it takes for it to travel around the sun.
