Venus is much brighter than Mars. Only the Moon and the Sun are brighter than Venus.
When Mars is in retrograde motion, it does not affect its brightness. Mars will continue to appear at its usual brightness in the night sky regardless of its retrograde motion. Retrograde motion refers to how the planet appears to move in the sky, not its actual brightness.
Like the moon, all the planets get their apparent brightness by reflecting light towards us from the Sun. At some stages Mars is reflecting more light towards Earth, so it appears to be brighter. Also, sometimes it is closer than at other times, so it appears to reflect more light towards us.
Jupiter is a lot bigger, so it looks brighter even though it is further away. Mars can be quite bright for a few weeks around the time of opposition, which happens every 780 days or just over two years, the next time 22-05-2016.
Mars is visible from Earth because both planets orbit the Sun. When Mars aligns with Earth in its orbit, it can be seen in the night sky. Additionally, Mars reflects sunlight back towards Earth, making it visible to the naked eye.
Well, we can assume so, at least with the aided eye. Phobos and Deimos, the two moons of Mars, can easily be seen from Earth with the correct telescope, so it would be even easier on Mars, with less atmosphere and a shorter distance.
Saturn is brighter than Mars in our night sky. Saturn's rings reflect more sunlight, making it appear brighter from Earth. Mars is usually visible to the naked eye and has a reddish color, while Saturn has a yellowish tint.

Venus is the brightest, then Jupiter and mars. All of these can potentially be brighter than sirus, but have to be well placed in their orbits relative to us.

Venus, at its brightest, is brighter than any other planet. However, when it's not at its brightest, there are a couple of others than can be brighter if they're near their brightest, Mars and Jupiter being the most notable.
If you are referring to the albedo or the natural light that is emitted from an object then the answer is the Moon. The Moon's albedo is .12, while the albedo of Mars is .15. Basically, this means that Mars is brighter, however we see the moon as being brighter because we are much closer to the moon than to mars. Alternatively, if you are asking which has more sunlight falling on it, the answer is the Moon. Mars is further from the Sun than the Moon, so there is less sunlight falling on each square inch of the Mars than on the Moon.

Look up in the sky and you will see. Polaris is actually quite dim, compared to other stars and planets. Even at it's dimmest, Mars is brighter than Polaris.
The brightest object as seen from us is the Sun.The next-brightest objects are the Moon, Venus, Jupiter, and Mars (on rare occasions, Mars can actually be a bit brighter than Jupiter).
Both Mars and Venus are visible in the East before sunrise. Venus is brighter, and more white colored; Mars is higher, a little dimmer, and distinctly reddish.
Jupiter is a lot bigger, so it looks brighter even though it is further away. Mars can be quite bright for a few weeks around the time of opposition, which happens every 780 days or just over two years, the next time 22-05-2016.
