No.
Gravity is the pull from matter. Less matter means less gravity, so yes.
Yes it does. All objects have gravity but the amount of gravity depends on the mass of the object.
The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force attracts the planets in, against this tangential velocity. If the planets were to gradually slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
Yes planets get colder when further away from the Sun.
Yes. While not considered planets, dwarf planets are still massive enough to be rounded by their gravity.

Yes. All planets have gravity. Earth is one of those inner planets.
Yes they are the sun has gravity that holds the planets in place.
Yes it does. All objects have gravity but the amount of gravity depends on the mass of the object.
Yes. All planets have gravity.
Yes. All planets have gravity.
Yes it does
Yes. All planets have noticeable gravity.

Yes, because on different planets you are being pulled down by a different mass. this help me so much
yes it does
Yes.
