1 balloon's worth.
That's like asking "how big is a rock". Do you mean a pebble, or a bigger rock, or a big rock like a boulder, or a truly huge rock like a mountain? Actually, it's even worse than that, because with a balloon pressure becomes a factor.
The amount of air a water balloon can hold depends on its size and how tightly it is inflated. As the balloon expands with air, the water inside compresses, allowing more air to be added. However, there is a limit to how much air a water balloon can hold before it bursts.
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
A long balloon typically holds more air than a round balloon due to its shape and design, which allows for increased volume capacity. The elongated shape of a long balloon allows it to expand more when filled with air compared to a round balloon.
A standard balloon may hold about 2 litre air at normal temperature
The amount of weight a balloon can hold depends on the size and type of balloon. A standard latex balloon can typically hold a few grams of weight before bursting, while a large helium-filled foil balloon can hold several ounces. It is important to check the manufacturer's guidelines for each specific type of balloon to ensure safe handling.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
A hot air balloon can typically hold around 1,000 to 2,000 pounds of weight, including passengers and cargo.

Putting an air-filled balloon in a refrigerator will cause it to shrink.
No it decreases
A water balloon is filled with water, and other balloons are filled with air or helium.
The duration an air-filled balloon stays inflated can vary based on factors such as the quality of the balloon, temperature, and air pressure. Under normal conditions, an air-filled balloon can stay inflated for several days to a week before starting to deflate.
