I live on Earth, as do all other humans. Where are you from?

Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
Yes. Surface gravity on Ceres is about 3% that of Earth.
Yes it does but not as much as earth does. Every object that has mass also has gravity.
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
Mars has a weaker gravity than earth because it is a smaller planet and is smaller than
It's not known for certain but it is believed to be around 2g/cm3, probably inferred from Pluto which is about the same. The Earth for comparison is 5.5153 g/cm3
There isn't. The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.
Earth has a much greater mass than Pluto does, and therefore has stronger gravity.
Venus has a gravity of about 0.904g, which is 90.4% of Earth's gravity. This means that if you were on Venus, you would feel almost the same weight as on Earth, but less than the Moon.
The moon has gravity but the earth has more because living people live in the planet.
The atmosphere is held in place by the earth's gravity. Gravity is related to mass, the more mass a planet has, the more gravity. A much smaller planet like mercury or a body such as the moon will have less gravity, not enough to hold an atmosphere - the gravity is not strong enough to prevent the gas particles from escaping into space.
