Nothing can stop gravity.
It goes right through a vacuum, planets, moons, stars, neutron stars, black holes, even event horizons, as though they were not there.
Distance reduces gravity, but it never really disappears entirely.
Einstein was wrong about it being indistinguishable from an acceleration. Accelerations do not taper off as gravity does.

Mass
If you hold a mass above another mass and isn't connected in anyway to the mass below then the mass on top will cancel out the gravity that is created by the mass below.
For example on earth. If you held a very dense, heavy mass above earth then there will be a small area very close to the hovering mass where the gravity will be reduced. The problem will be the energy required to hover the mass above earth with out any connection to earths mass.
Maybe hover it with a hotair ballon? Helicopter? But the mass of this object would have to be huge and very dense to has an impact. Something like solid lead sphere with a weight of a 1000000 tons.

Nothing really stops gravity. We always have gravitational forces acting upon us. Black holes actually have an extremely high gravitationan pull, such that no light can escape; this is an extremely strong force. Also, vacuums still have gravity, but very low pressure and no wind resistance.
The only way you can be free from gravity is to be by yourself in free space with nothing else in existence, because the smallest piece of matter will exert a gravitational pull against you. (Every object around you actually exerts a gravitational force on you, and you on it, but these forces are extremely small).

It has been thoroughly tested with magnetic fields, and zero gravity has been achieved for some time now. The problem is that it requires an incredibly intense gravity field which consumes a ridiculous amount of energy.
Those experiments were successful on small animals (frogs, grasshoppers etc) and other small objects, but anything bigger is far too expensive and power draining.

No,gravity is a manifestation of space associated with matter.
The field permeates all of matter and it"s surroundings.
It is possible to simulate the absence of gravity but not to block it or shield it.

Good question.
There is such a thing as superfluid that can move against gravity (up), but nothing that can actually shield gravity.
And there's no such thing as a vacuum. If there were, the sun wouldn't hold the earth in orbit. So that's not it.

Free Fall.
According to Einstein's way of looking at it, being in free fall is the same as being "out" of the gravitational pull.
You just have to stop fighting it!! Go with the flow!

nope not currently. It's not actually a force, it's like a dip in the road. Objects follow the path of least resistance and so they dip and turn as the "road" dips and turns. For that reason, there's no force to cancel out or try to get out of phase with.

yes an acceleration more important than the gravity ... now you can search

Exiting the earth's atmosphere still doesn't stop it. You will always be in some kind of gravitational pull in space. When you leave earth, you'd be in the sun's gravitational pull.
Energy just helps you control yourself in gravitational energy.
So, No.
