The answer depends on what substance is in the balloon and the substance which forms the exterior environment. Since there is no information on either, it is not possible to answer the question.
a balloon float on water
Fill a balloon part way with helium, make an animal out of it and have it float.
Any gas with a density higher than air. Carbon dioxide will do it, krypton is denser still, and will make it drop quicker. There are others too.
I can give you several sentences.The ball will bounce higher if you drop it onto the concrete instead of the grass.Kittens bounce around chasing string.If you don't have enough money in the bank, your check will bounce.
Heilum combined with the light material of the balloon make it as light as air making it float.

The key word there is float. There is nothing in space for a hot air balloon to float on.

yes
Yes CFC's are much heavier than air. If you filled a balloon with CFC's, it would drop, not float away.
Heilum combined with the light material of the balloon make it as light as air making it float.
The balloon will either float or pop
Helium goes into a balloon to make it float.
you drop it.
because helium has less density
