A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
When mars is in retrograde motion will it appear brighter or dimmer?

Is it true that a stars absolute brightness is when its seen from earth?
No - a star as seen from earth is it's apparentbrightness. It's absolute brightness is measured by astronomical instruments. The brightest visible star from earth is Sirius, in the constellation Canis Major. Spica, in Virgo, has a much higher absolute brightness than Sirius, but Sirius is much closer to earth, so it is apparently brighter than Spica.
How do you draw a diagram showing which moon would be brightest from Jupiter?
The four main moons all look about the same brightness as seen from Earth, and they are all at about the same distance from the Earth. That means that their brightness seen from Jupiter would depend on their distances from Jupiter.
