Yes, a vacuum is just removing the air from an area. Gravity is the pull of the Earth on an object. In a vacuum, air resistance becomes negligible, and things fall at the same rate, gravity.

Gravity Requires 2 objects (both create a gravitational field but you need a second to measure it). However, this is where it gets complicated, in a vaccuum theres is no mass (or at least no pressure) and is there is no mass then the is no gravitational force. However, if your asking can gravity affect something through a vaccum then the answer is yes because while gravity requires mass to exist it exists as a result of mass not inside of it.

Yes, gravity acts in a vacuum; a vacuum is a space that is basically empty of matter (such as air/gasses) causing the pressure inside to be much less than, say, the normal air pressure we every day here on earth. Matter in a vacuum is still subject to gravity.
The effect of gravity is what keeps the planets in our solar system orbiting around the sun. It gravity were to, suddenly, be gone, the planets would fly off into space.

Yes, of course. What is absent in a vacuum is air which would otherwise cause friction on a falling object, if that is the reason you ask this question. Friction will affect the acceleration due to gravity. That is why when they give a value for acceleration, they specify " in a vacuum".

yes. It is not dependent on conduction by material (the way heat is). It is dependent on the mass of the two objects and the distance between their centers. Look at the universal gravitation equation
F1 is proportional to (m1 +m2)/d squared. It is not dependent on the amount of material between the objects. Now if you define a vacuum as containing nothing (including the two objects) then no it cannot. It depends on the definition of vacuum.

an common Eg for relativity : you're seeing a woman who's attractive in some Musical keep. then you fairly left to your place. After some days you're questioning on the subject of the musical keep which you visited, as we talk your suggestions will make you to bear in suggestions that attractive lady too. it is the relativity. the stunning lady is proper with the musical keep. I belive you understood

in M theory I believe gravity is transmitted primarily thru the 11th dimension which is all around us but too small to detect.

Yes, since space is nearly a vacuum and we are still in orbit around the sun.
