This falls into the realm of urban folklore. One CAN breathe in freefall - if it were necessary. However, due to the high speed of terminal freefall (and much higher speeds in vertical freefall dives), the jumper's body is exposed to O2 molecules at a much higher rate than someone walking around on the ground. The body is able to absorb the necessary O2 through the skin. This is why jumpers flap their cheeks in freefall, it presents a larger surface area to the airstream for oxygen osmosis. Once under canopy, the jumper resumes breathing normally.
This is also why jumpers do not jump on cloudy days or when they might risk going through clouds. The moisture in the clouds can condense on their exposed skin surfaces preventing the absorption of the necessary oxygen resulting in suffocation.

Well this is from the military way of diving :
In all jumps from above 10,000 feet, free fall to 10,000 feet or less before pulling the ripcord if you can. This will reduce your exposure to cold, anoxia, enemy action and lessen the opening shock of the parachute. If you do not have bail-out oxygen equipment, just hold your breath and dive out. Then continue to hold your breath as long as possible before pullling the ripcord.
heres another
Yes, breathing in freefall is possible unless you are panicing (i.e. holding your breath, hyperventilating) - lol! Just inhale, you have wind rushing at you at about 120 mph
No, it does not feel like the "rollercoaster" sensation when you exit the airplane.
No, you don't get the sensation of falling. As you get lower in altitude you can start to see the ground coming up at you (called ground rush). For example, if I'm lower than 2000', I can tell cuz I've seen what 2000' looks like about 800 times, and when I'm lower the ground looks different. Mostly bigger and coming up faster
Basicily, you have to breath at a calm pace as many times as needed or you will end up hyperventilating or holding your breath.
