Generally free fall recreates zero G. Air resistance will change things if you're falling like a parachutist.
What the astronauts experience is exactly free fall, but without a strong wind causing terminal velocity as parachutists.
For about 30 seconds at a time, special aircraft can fly in a manner that simulates free fall (also avoiding the wind (at least on the inside of the aircraft).
There is no place in the universe that has zero gravity. No matter where you are some type of gravitational force is acting upon you. So there is no way to create zero gravity even in the vastness of space.
The only place where there is no gravity is in space, infinitely far from any mass. To create the conditions that your body interprets as zero gravity, choose one of these: -- Jump from an airplane or balloon. Do whatever skydivers do to minimize your air resistance and fall as fast as possible. That puts you close to zero gravity, but not exactly. -- For brief periods of zero gravity, like 30 seconds at a time, take the training and get a ride on NASA's "Vomit Comet" airplane. -- Get into Earth orbit somehow.
The gravity at the center of the Earth is zero because the mass around you causes gravity to be in equilibrium. It is pulling in all directions equally, resulting in a net zero gravitational force at the center.
At the center of earth or any other heavenly body.
Gravitation can't be cancelled or shielded. You can have the appearance of zero gravitational force when you are in free fall. Without going into outer space, this can be maintained for a few seconds at most.

There are no permanent zero gravity places on the surface of the Earth. However, temporary experiences of near-zero gravity can be achieved in specially designed aircraft called "vomit comets" that create parabolic flight paths to simulate weightlessness. Additionally, some amusement parks offer rides that create moments of weightlessness for thrill-seekers.
No.
Yes. At least, the gravity resulting from planet Earth.
the pen which is used on earth is not made considering zero gravity effect if this pen is used in space the ink can flow out easily so astronaut has made a pen considering zero gravity
Yes; the gravity from different sides should cancel, for a net result of zero gravity.
No. At the centre of the earth the acceleration due to gravity is ZERO
It does not. Earth's gravity is the result of Earth's mass.

Acceleration due to the earth's gravity is zero at the center of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. Simplistically, acceleration due to gravity decreases as distance from the center decreases. At the center the distance is zero, hence gravity is zero.

when object fall free like at centre of earth that we call freefall with zero gravity.
