They use parachutes on their module to slow down and then land safely in the water to be fished out later.

A meteor. Technically, a "meteor" is the flash of light itself. Once the rock hits the Earth's surface (IF it survives) it is called a "meteorite".
Yes it is.
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.

No, the earth's atmosphere reflects and absorbs x-rays, so they do not make it to the surface.
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
mesosphere
Thermosphere, it is also the atmosphere with the highest temperatures.

As a rock is falling through the atmosphere, it is a meteor. When it hits the earths surface, it is a meteoroid.

When Earths surface is heated it radiates some of the energy back into the atmosphere as "Infrared Radiation."
