The astronauts on a space mission usually have just the air they take with them (there have been some experiments in storing liquid gases to mix). The carbon dioxide is removed from the air, either by chemicals such as lithium hydroxide, or by using hydrogen that is electrolyzed from fuel cell water to recapture oxygen (Sabatier reaction). Oxygen is added from the fuel cell water and reserve tanks. All of this means that a long-term mission is limited by the supplies of hydrogen and oxygen and water they bring along, or are delivered by resupply.Space vehicles can harness substantial energy from small reactors, fuel cells, and solar panels, but they cannot obtain any air or water in space.

Is it true that each time you breath you get a fresh supply of oxygen?
Yes. Though the air you're breathing might not exactly be 'fresh,' you do get a fresh supply with every inhalation.
How would you go about storing the extra oxygen and air that would continuously provide fresh air to the astronauts?
having air pockets in the resperater of the astronuat's suit
Is the fresh air come through the AC If any then how many?
Yes, its 1 to 10% of your supply air. ;-)
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use radios.
Why is compressed oxygen used instead of compressed air in space?
Oxygen is the component of air that we consume, so it must be continuously replaced as the astronauts breathe it. The the other components of air, mostly nitrogen, simply come from the initial air supply and do not need to be replaced.
Breath of fresh air or breathe of fresh air?
Its breath of fresh air.
Was Neil Armstrong low on air supply while on the moon?
The Lunar Module and the astronauts' spacesuits carried plenty of oxygen for the Moon landing, but they were critically low on fuel to leave.
