Yes. But that has not proven to be a serious limitation.
How many objects can you name that have no mass ?
No, gravity acts on all objects regardless of their weight. The force of gravity is dependent on the mass of an object, so heavier objects will experience a stronger gravitational force than lighter objects. However, even very light objects, such as feathers, are still subject to the force of gravity.

gravity and drag
yes
Mass is the property of matter on which gravity act upon.
Gravity only acts on objects with mass. Electromagnetic radiation (light, etc.) does not have mass, so gravity would not act on it.
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.

yes
Mass is the property of matter on which gravity act upon.
Gravity is a force that acts on every object in the universe. If two objects have mass, there will be a force due to Gravity between them, proportional to their masses and inversely proportional to the square of their distance between each other.

No force "acts on the force of gravity". Rather, both gravity and other forces - such as drag - will act on objects.
Not quite. Gravity can act at any distance. However, in practice, when the distance between the objects is great, the force of gravity may become insignificant.
Are you even human? There is no way that a functional human doesn't know what gravity is.
