In physics, the force of gravity is typically considered a negative force because it acts in the opposite direction to the motion of the projectile. Gravity causes the projectile to decelerate and move downwards.

Gravitational force pulls downward. If you take the upward direction as positive, then any force that pulls downward will be negative. It is a matter of definitions; you can just as well define up as negative, and down as positive. It doesn't really matter much, one way or the other.
Yes, a force such as gravity acts on a projectile, influencing its trajectory and motion. The force of gravity accelerates the projectile downward, affecting its path and causing it to follow a curved trajectory.
The only force acting on a projectile is gravity. It causes the projectile to accelerate downward and follow a curved path. The horizontal motion of the projectile is not affected by any other forces.

A projectile is considered to be in free fall when the only force acting on it is gravity. This means that the object is not being propelled or pushed by any external forces, and it is only subject to the force of gravity causing it to accelerate downward.

Zero, assuming there is no air resistance. Gravity does not do work in the horizontal direction during the descent phase of projectile motion because the force of gravity and the displacement are perpendicular to each other, resulting in no work being done by gravity.

No, a feather falling in a vacuum is not considered projectile motion. Projectile motion involves an object being launched horizontally with a certain velocity while experiencing the force of gravity, causing it to follow a curved path. In a vacuum, there is no air resistance or drag force acting on the falling feather, so it falls straight down due to gravity.
Gravity affects catapults by pulling the projectile downward once it is launched, influencing its trajectory and distance. The force of gravity must be considered when designing a catapult to ensure that the projectile reaches its intended target. Additionally, the angle and force of the catapult must be adjusted to account for the gravitational pull on the projectile.
The only active force acting on a projectile is gravity. Once the object is released, the only force affecting its motion is the force of gravity pulling it downward.
