Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no real atmosphere due to its small size and proximity to the sun.
The atmosphere on Venus is very thick, giving it a high surface pressure, some 93 times that of the Earths. Carbon Dioxide makes up around 96.5% of the atmosphere with around 3.5% Nitrogen. There are also small amounts of sulfur dioxide (0.0015), carbon monoxide (0.0017%), water vapour (0.002%), argon (0.007), helium (0.0012%) and Neon (0.0007%)
Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, with 0.93% Argon and 0.038% Carbon Dioxide. Around 1% of the atmosphere is water vapour, with traces of other gases such as Neon, Xenon and Carbon Monoxide. Earths atmosphere is thicker than Mars', but not nearly as thick as Venus'.
Mars has a thin atmosphere, mainly of Carbon Dioxide (95.32%). Nitrogen makes up 2.7%, Argon 1.6%, Oxygen 0.13% and Carbon Monoxide makes up around 0.08%. There are other trace gases such as Water Vapour, Neon, Krypton, xenon, Molecular Hydrogen and Nitric Oxide. Mars' surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
Jupiter's atmosphere is mainly Hydrogen (around 90%), Helium (around 10%), with small amounts (minor gases) of Methane (around 0.3%), Ammonia (0.026%), Hydrogen Deuteride (0.003%), Ethane (0.0006%) and Water vapour (0.0004%).
Saturn's atmosphere is mainly Hydrogen (around 96%), Helium (around 3%), with small amounts of Methane, Ethane and Ammonia.
Uranus' atmosphere is mainly Hydrogen (around 83%), Helium (around 15%) and Methane (around 2.3%).
Neptune's atmosphere is mainly Hydrogen (around 80%), Helium (around 19%) and Methane (around 1%).

If each planet has thick atmosphere why cant you breath it?
The composition of a planet's atmosphere, including the presence of oxygen, is crucial for human respiration. Depending on the composition, a thick atmosphere might not contain enough oxygen for human survival, making it impossible to breathe. Additionally, other gases or compounds in the atmosphere can be harmful or toxic to humans.

Ceres is not a planet; it is a dwarf planet. It does not have an atmosphere.
How is the surface gravity of the terrestrial planets related to the type of atmosphere that they have?
The acceleration of gravity at the surface of each terrestrial planet is proportional to the mass of each planet and inversely proportional to the square of the planet's radius, with Newton's gravitational proportionality constant, and is not correlated in any way with any characteristic of the planet's atmosphere. In other words: It ain't related.

How many planets are in the atmosphere?
An atmosphere is a layer of gas that is part of a planet, and usually surrounds it solid part, if there is a solid part. so for each planet, there is one and only one plant in its atmosphere. The earth is the only planet in the Earth's atmosphere; Mars is the only plant in the Martian atmosphere; etc.,
