Higher speeds can be attained if the skydiver pulls in his limbs . In this case, the terminal velocity increases to about 320 km/h (200 mph or 89 m/s), which is also the maximum speed of the Peregrine Falcon diving down on its prey.

On August 16th, 1960 U.S. Air Force Captain Joe Kittinger almost breaking the sound barrier during a free-fall from the high altitude balloon Excelsior III, at an altitude of 102,800 feet (approximately 20 miles), hitting a speed of 614 mph (274 m/s) as reported by National Geographic. This made Captain Kittinger the fastest human on the planet.
Here's a video of the jump.

Why anyone would want to jump out of a perfectly good airplane is beyond me.

That aside, terminal velocity, if you're as clean as can be, (ie arms at your side, head down, legs straight,) is in the vicinity of 180 mph. A diver will experience the same profile drag that an aircraft would experience in normal flight and in free fall, weight isn't as much as much a factor as aerodynamics.

A 6' tall man, weighing 300#, even in a clean dive, will descend at a slower rate than a 6' tall man weighing 200#'s. As they descend, and air density increases, the gap between the two men would increase.

If we assume that the two men are using the same make and model parachute with the surface area and deploy the 'chutes at the same altitude, the heavier man might hit the ground first while the lighter man will be faster in free fall.

I believe you can reach a max speed of 120 MPH

That, strictly depends on how fast the plane is going - whatever speed a plane can do, if you jump out, you'll immediately hit the same speed

Total Velocity is 125 mph (give or take a few tenths)

You mean in free fall? maybe 180 mph. You can use gear to streamline your body and go a little faster.

120 mph or 54 meters per second

it depends on how you are doing it. If you spread your arms and legs out in the normal manner it's about 120 mph. However if you tuck your arms in flat and point yourself like an arrow downwards you can go about 200mph.

terminal velocity. Something like 120 mph?

terminal velocity(the top speed of a free falling object) for a human is about 120mph
