Their's a person who can float using air inflation, he/she is on furaffnity

Easy. She jumped, and the cameraman got the right moment.

You can always count on nineteenthly for great info on physics and whatnot.
Also if I might add to this there's a music video that has a guy in an inflatable suit floating away.

Figured it was worth posting here anyways.
Welcome!
Sorry, it can't be done in the atmosphere of this planet. If someone weighs 50 kg, their density would have to be lower than 50 kg worth of air. Air has a density of about 1.4 grammes per litre, so 50 kg of air is more than 35 cubic metres. That would be a sphere 4 metres in diameter but that assumes a vacuum. If it was hydrogen, that would add 3 kg of weight.
You can increase the density of the air around someone by increasing the pressure, and if you put them in a suit, that could be increased further, or you could surround them with a dense gas such as sulphur hexafluoride. If there was a pressure 70 times that at sea level, they would then need "only" about 500 litres of gas to do it, but that's still many times the capacity of the body. It might just be possible with subcutaneous hydrogen, as that would mean a sphere about a metre across, I think.
