5. All of the above

The distance is an inverse square effect. Size is not so important as all stars apart from our sun are essentially point sources. Total energy is important but more critically the brightness is more a funstion of the temperature (particularly when you are only measuring in the visible spectrum)

All of the above...also if the star is travelling toward or away from us.

Plus, add in factors such as atmospheric conditions where the star is being viewed from (pollution, moisture etc)
