Nothing. Gravity exists in vacuum as well.
There IS gravity in a vacuum - there's no AIR.
When a hollow plastic ball and a solid metal ball is a dropped in a vacuum and gravity is the only force acting on the balls the balls will fall at the same rate. Being that this is a prediction answer may vary.
Yes if there is no gravity
Yes. Gravity attracts every speck of mass in the universe to every other one, even though in almost all cases, there's nothing but vacuum between them.
A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.
Whether or not you float has nothing to do with vacuum. You float because you are too far away from the earth (or other massive objects) for their gravity to have any noticeable effect on you. It just so happens that this occurs in space where natural vacuum may be found.

Vacuum filtration is far faster.
No - gravity acts across the vacuum of space - this is how the moon affects our tides.

Gravity waves travel as small distortions in space and time.

Not necessarily. A vacuum is merely any volume having a density lower than an arbitrary amount.
