Not "affect"; the word is "effect" in this case. Yes, air resistance has an effect on projectiles.
Not directly. Air resistance depends on an object's shape and type of surface.
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
size , shape , and speed of the object
Air resistance increases and terminal velocity decreases when the parachute has opened.

The resistance caused by the aircraft moving through air
it gets faster.

Normally, air resistance slows an object and this does not help motion, it impedes it. Lift, which is an aerodynamic force, is very helpful and it's caused by air resistance. This allows a plane to lift off and stay in flight.
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.

If air resistance can be neglected, there is no effect. If there is air resistance, the general tendency is for more massive objects to fall faster. In places like the moon, where there is no air, a feather and a rock fall together.
