The low temperature inside the freezer causes the air inside the balloon to contract.
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.
A hot air balloon is hollow (naturally) and is filled with the hot air that gives the balloon lift. By surfing the web a bit, one can probably find a picture that gives at least a partial view of the inside. I would doubtless have been taken by someone in the basket of the balloon, but there may be a shot of a an airborne balloon at low altitude taken by someone on the ground.
One of two reasons, either the gas inside the balloon is lighter than the air around it, as would be the case if the balloon was filled with helium, or the gas inside the balloon is hotter than the air around it, as is the case with hot air balloons.
It would spoil the alcohol due to the plastic in the balloon, but it wouldn't doa anything else, unless the balloon or the alcohol was hot, the the balloon would pop.
The balloon would get larger as the air pressure outside it dropped. At some height, the balloon would get large enough to burst.
Putting an air-filled balloon in a refrigerator will cause it to shrink.
It would shrink (according to Charles's Law).
The balloon would shrink because the average kinetic energy of the gas molecules in the balloon decreases when the temperate decreases. Go and try it is a pretty fun!

If the balloon is filled with water, and the water freezes, the balloon will expand and may burst. This is because at temperatures below 4ºC, water begins to expand and as it turns to ice, it has a larger volume than when it was liquid.
Depending on how cold the cooler is, the water balloon what shrink from the cold and the water would remain liquid, or it would freeze and probably burst.
the balloon's volume would decrease!!!

Simple things are not always simple! Firstly, the air inside the balloon would expand, increasing the pressure, which would tend to make the balloon expand. However, latex tends to shrink as heated - its complex molecules change shape - which would tend to make it shrink! Which would win? Well, there's always one way to find out - try it! One benefit: If you blow one up really hard, you'll probably get it to burst first!
First, the balloon would float to the ground. After that, nothing special happens to the balloon because you filled it with oxygen.
A balloon filled with hydrogen can explode.
