The sun on Mars looks a little smaller and dimmer as it is further away. Compared to the Earth, the daylight brightness on Mars is only about 40-50% of the Earths. The sky has a reddish hue, due to the red dust in the atmosphere.
Mars if farther from the sun than the Earth is, so it gets less sunlight, but there is still sunlight on Mars - during the day.
Mars gets LESS sunlight than Earth does, because of its greater distance from the Sun.

Reflection of sunlight
Well first of all Mars has a tilted axis just like Earth so that would result in the division of sunlight on different areas of Mars and that is how they think that Mars has seasons.
There is enough sunlight on Mars to support photosynthesis, but factors other than sunlight make it inhospitable. Mars is too cold to live on outside of a heated shelter and the atmosphere is too thin to support any sort of Earthly life.
Lots
not much
No. Mars is farther out, so the sunlight is more dispersed out ther.
All things being equal, sunlight on Mars at aphelion would be about 36% as strong as sunlight on Earth. But Mars has a thinner atmosphere, so this will brighten it a little. Because your eyes adapt to the available light, the difference would be less noticable. Without a brighter comparison (sunny day vs. cloudy day here), the light would not seem intrinsically less. Since the Sun shows a smaller disk on Mars, shadows are sharper.
It does get sun but not as much as mercury and Venus
The sun shines on Mars, just as it shines on the Earth. Since Mars is farther from the sun than the Earth is, it gets less sunlight.
