They are essentially in a state of permanent free-fall. Their ship is falling to earth at the same rate as the curve of the earth is falling away form them; ergo continually falling.
It has nothing to do anything 'anti-gravity'.
Because of free fall in orbit, astronauts experience a continuous state of falling towards Earth while moving forward at a high speed. This results in a sensation of weightlessness, giving the appearance that they are floating or flying inside the spacecraft.
Because of free fall, astronauts in orbit appear weightless and float within their spacecraft. This is due to the spacecraft and everything inside it, including the astronauts, all falling towards Earth together at the same rate. The sensation of weightlessness is a result of this continuous state of free fall.
Stars appear as distant points of light from orbit, similar to how they appear from Earth but without the interference of the atmosphere. Due to the lack of atmospheric distortion, stars appear brighter and clearer in space. The darkness of space also allows astronauts to see more stars than we can from the surface of the Earth.
Yes. Gravity is what keeps them in orbit. If it were not for gravity, those astronauts would continue out into space in a straight line.
Weight is an expression of the gravitational force acting on an object. When the space shuttle is in orbit around the Earth, it is held there by the Earth's gravity. Since gravity is still acting on the shuttle and the astronauts inside, they still have weight. They are described as "weightless" because an object in orbit is in a constant state of free fall.
Astronauts in orbit experience weightlessness because they are in a state of continuous free fall towards the Earth. This creates the sensation of floating in space, as there is no force pushing against them to create the feeling of weight.

In orbit, astronauts appear weightless and float because they are in a state of constant freefall towards Earth. Due to the lack of air resistance and the gravitational pull being the only force acting on them, they experience the sensation of weightlessness.

No.

no they can weigh more or less depending which planets orbit

The Earth orbit in which satellites appear to be stationary is called the, "Geostationary Orbit". Some call it a synchronous orbit.
In recent years astronauts have gone to the International Space Station, which is in a low orbit around Earth.
