How many G's when falling in the air?

You experience ZERO g force when in free fall.
If you are falling in air at terminal velocity you experience 1 G force. Just as you do when sitting in a chair.

At intermediate points you experience a force of more than zero but less than 1 G

Incidentally when you FIRST open your parachute ( in air of course ) then you experience a force of many G until you slow down.

THEN you once more experience 1 G because once more you are at a new terminal velocity.

Your acceleration starts out at 1 g and decreases gradually. When you are at terminal velocity, that means you're moving at a constant velocity. No acceleration. 0 g's.

"When in free-fall, you experience 1G"

No. 1G (you mean 1g) is not your acceleration. It relates to your perceived weight.

When you are standing you experience 1g.
When you are in free fall you experience 0g.

With air resistance, you accelerate only until you reach terminal velocity. And the size of the acceleration varies during the fall. And acceleration depends on many factors (e.g. if you have a parachute!).

So your question can't be answered.

About 300. First time I jumped "AIRBORNE" HOOOOOOAH! I musta said, "OH GEE, OOOH GEE!" at least that many times.

Depends. But when you reach terminal velocity, you are no longer accelerating by definition. So you have a net G = 0.
