Mercury
Venus and Mars are the least alike in our solar system. Venus is a hot, inhospitable planet with a thick atmosphere and surface temperatures hot enough to melt lead, while Mars is a cold, arid planet with a thin atmosphere and surface temperatures that can reach below freezing.

Venus has an atmosphere made up of hot swirling clouds of carbon dioxide, which create an intense greenhouse effect and contribute to its extreme surface temperatures.
It depends on how far away the planet is from a star. If it's close, it's hot. Also, if the planet rotates on its axis there would be a big day-night temperature difference.
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.

The outside layers of the atmosphere are very cold, as they get little heat from the Sun. The surface is unreachable beneath the hot, extremely dense lower atmosphere.
Venus has a hot, turbulent atmosphere dominated by carbon dioxide. The thick atmosphere traps heat, creating surface temperatures high enough to melt lead.
Venus' atmosphere is hot because of its thick layer of carbon dioxide, which traps heat from the sun through a greenhouse effect. This causes the planet's surface temperature to rise to extreme levels, making it the hottest planet in our solar system.

Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.
No, it's a planet.
Neptune is an "Ice Giant" planet. Neptune's atmosphere is composed primarily of hydrogen and helium. We can not see the surface but we believe the surface is primarily composed of ices and rock and the planet has a hot core.

Hard to say, as the distance from the star will also factor in, but in general, thin atmosphere would mean no insulation, it would be cold. Mars is a classic example of a planet having a thin atmosphere. It is extremely cold on Mars and has a small amount of carbon dioxide in it's atmosphere but is not in high enough concentration to warm the planet. Mercury has no atmosphere and it is hot and cold depending on which part of the planet is facing the Sun. Venus has a very dense amosphere and it is very hot, no matter which surface is facing the Sun.

As the planet Jupiter has no surface, the temperature of the "surface" cannot be measured.
