Humans may get weak in a lack of gravity situation, due to the lack of use of certain muscles.
Not only in space - gravity is universal. The force of gravity is affected by the distance, and by the masses involved.
The ball will not be affected by drag. Only gravity will affect its trajectory.
There is gravity in space. Gravity is everywhere. You can never escape gravity.
There is gravity in space. Gravity is what makes orbits possible.
In space, there is no gravity to overcome. The chllenge to astronauts is how to deal with the lack of gravity.
Gravity
Zero gravity is a space word. It begins with the letter z.
Yes, there is an object affected by only gravity. Stars and other floating space debris are only affected by gravity in space, as long as the objects do not touch each other.
Such an object is said to be in free fall.
they can be yes.
If by "gravity neutral" you mean "not affected by gravity" the answer is none. Gravity is an attribute of curved space-time and thus everything in space-time is affected. Even massless photons curve in the presence of massive bodies.

Anything that isn't affected by the Sun's gravity will not revolve it. Almost anything outside of our solar system will not be affected by the Sun's gravity. But that's not to say that they aren't being affected by another star's gravity.

The ball will not be affected by drag. Only gravity will affect its trajectory.
Gravity might have a hold on you or you will grow a couple of inches and lose weight. It depends on how long you are staying in space.
Gravity isn't necessary for human life, as we can see on the International Space Station, where crew members spend months with no gravity at all. But even if gravity were absolutely essential, that would not be a problem on Mars, which has plenty of it.
