Mercury and Mars.
(Venus has a thick atmosphere, much thicker than Earth's.)
(Titan, Saturn's largest moon, has an appreciable atmosphere, thicker than Earth's and is the only moon in our solar system to posses an atmosphere.)
Mercury probably doesn't have (much of) an atmosphere because the solar wind would carry it away into space.
Each of the four inner planets has an atmosphere, except Mercury. Mercury is too small and close to the sun for its gravity to sustain a proper atmosphere, although a tenius and unstable exosphere it thought to exist.
None of the planets has a single ring, all of the gas giants have more than one.
air and gasses and for some no atmosphere
They don't all have thick atmospheres. Mars has a thin atmosphere and Mercury barely has an atmosphere at all. No planet in the solar system other than Earth has significant amounts of elemental oxygen in the atmosphere. This is the gas we get from breathing. Additionally, the other planets are too hot, too cold, or have pressure that is too high or too low for us to breathe.
The thinnest atmosphere belongs to planet Mercury . . . it may have no atmosphere, at all.
The inner planets Mercury, Venus, Earth, Mars are are all relatively small, they are all rocky, they all have a relatively thin atmosphere.
No. Only Venus has a really thick atmosphere. Mars has only a thin atmosphere and Mercury has almost no atmosphere.

Some dwarf planets, like Pluto, have thin atmospheres composed mainly of nitrogen, methane, and carbon monoxide. However, the atmospheres of dwarf planets are not as substantial as those of larger planets like Earth or Jupiter.
All the other planets in our solar system have atmospheres, but their composition varies. For example, Venus has a thick atmosphere of carbon dioxide and sulfuric acid clouds, while Mars has a thin atmosphere primarily composed of carbon dioxide. Gas giants like Jupiter and Saturn have thick atmospheres mainly made up of hydrogen and helium.
All planets in our solar system made of gas except for Mercury. Mercury is a terrestrial planet, composed mainly of rock and metal, with a very thin atmosphere.
None of the planets has a single ring, all of the gas giants have more than one.
They are not the same at all, Venuses atmosphere is very hot dry and thick, while Mars atmosphere is thin and cold. Though they have totally different atmospheres, both planets are going through the same processes, which makes them very similar.

they all have different gasses in there atmosphere
There are probably a very great number of planets in our galaxy with no atmosphere. Of the 400+ planets that we know of, we can only determine the presence or absence of an atmosphere for the 8 planets in THIS solar system; our technology is not yet good enough to study atmospheres from several light-years distance. Of the planets of this solar system, we are fairly sure that Mercury has no atmosphere to speak of. Of the other seven, we know that Mars has a very thin atmosphere, but enough to use a parachute in. If we include dwarf planets, we can say with some certainty that Ceres doesn't have enough mass to retain an atmosphere, and Pluto's atmosphere is almost certainly all frozen by now.
