It is similar to the composition of the atmosphere of Venus. They are both made almost entirely of carbon dioxide.
None. By definition a rocky planet is mostly rock. Venus, by far, has the densest atmosphere of the terrestrial planets, but the planet itself is mostly rock and is similar in composition to Earth.
Based on the distances provided, Planet A is Venus and Planet B is Saturn
It can vary substantially. Whether a planet is a Goldilocks planet is based only on its distance from the star it orbits. If a planet orbits at the right distance that it might be the right temperature to support liquid water, it is called a Goldilocks planet. The nature of the atmosphere would still be affected by factors such as the planet's composition, mass, and evolutionary history.
Neptune is the most blue planet, due to methane in it's atmosphere absorbing the red light. It's atmosphere is mainly hydrogen and helium though and the cold temperatures would be more of a concern than the actual atmospheric composition.
Eris has a frozen atmosphere.
Eris has a frozen atmosphere.
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere

It is a gassy planet like Jupiter, Uranus, and Neptune
An average temperature, stable atmosphere, and solid composition.

The planet's gravity. However, some atoms, or molecules, will escape, and the atmosphere will tend to gradually "evaporate". How fast this happens depends a lot on the planet's mass; also on the temperature and the composition of the atmosphere.

Their distance from the Sun as well as their atmosphere - presence or absence as well as its composition (if present)..
