Probably the Babylonians were the first to observe and record the presence of Mars, which would make it around 700 BC.
It has just two. They are Deimos and Phobos. These are the moons or natural satellites. There are also satellites from Earth, sent to observe Mars.

Yes, the phases of Mars can be observed from Earth. As Mars orbits the sun, its position relative to Earth changes, causing the planet to exhibit different phases similar to those of the moon. Through a telescope, you can observe these phases, from a fully illuminated phase (opposition) to partially lit phases (quadrature).
