A light year is the distance traversed during one year of travel at the speed of light. Hence, it is not a measure of time, but of length.
As far as I know, the only difference between solar flares and prominences is the shape. Both are streams of gases emitted from the sun, but prominences are in the form on an arc, and flares just shoot straight out.
Your third question doesn't really make sense. I think you may have made the error I mentioned earlier (about the light year being a measure of distance, not time).

A light year is the distance of light travelled in a year's time.
A solar flare is a sudden and brief brightening of the solar atmosphere in the vicinity of a sunspot that results from an explosive release of particles and radiation while solar prominence is an eruption of a flamelike tongue of relatively cool, high-density gas from the solar chromosphere into the corona where it can be seen during a solar eclipse or by observing strong spectral lines in its emission spectrum.

a light year is used only in space
