it blows up
The air we breath is about 21% oxygen (02), 78% is nitrogen (N) and 1% argon (Ar). The air is slightly less dense than 100% oxygen. The 100% pure oxygen will sink slowly into air, until the gases eventually mix and spread out. Therefore, 100% oxygen does not rise in the air.
No, because oxygen's density is heavier than the density of air.
Yes it does
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.

One balloon full? Nothing. We breathe Nitrogen constantly. It is only when you increase the proportion inhaled in comparison to Oxygen does it begin to have an effect. A constant stream of Nitrogen would suffocate you.
yes
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Helium is lighter than air and a balloon filled with helium may rise up.
That is because the Pressure inside the balloon caused by the filled pressure reached equilibrium at this point based on the height so can rise no longer.
First, the balloon would float to the ground. After that, nothing special happens to the balloon because you filled it with oxygen.
It is filled with a gas that is lighter than air.
because it doesn't have any oxygen in it.
CO2 is heavier than a mixture of 75% nitrogen and 20% oxygen.
I am not sure what you mean by 'depend' (please try and make your questions clear) but if you mean does the fact that a helium filled balloon will float (or rise) depend on gravity? Then the answer is Yes. if you were to take a helium filled balloon to the space station and release it inside, it would not rise, it would behave just the same as if you released a bunch of keys.
Until The Pilot Of The Balloon Cannot Breathe And Must Bring The Balloon Down Due To Lack Of Oxygen.
A weather balloon filled with hydrogen is also lighter than air, and will rise to great heights.
The composition of air is roughly 78% nitrogen and the remainder except a negligable amount of hydrogen is more dense than nitrogen. Therefore a balloon filled with nitrogen will be less dense then the surrounding air and thus will rise. The balloon will probaly not rise, as there is insufficient lift to overcome the weight of the balloon fabric. Are you sure you don't mean Helium, or Hydrogen?
