i dont know. Why dont you try making one and find out.
Air expands when it is heated. This makes it less dense than colder air. Hence, it has buoyancy, and tends to rise. If it is trapped in a balloon, it can take the balloon up with it, along with things attached to the balloon, as long as the buoyancy of the balloon exceeds the attached weight.
Assuming you mean hot air balloon piloted license, it depends. There are three different stages of it, student, private, an commercial. Each take about a year to obtain
A Balloon needs hot air to rise, the flame, which is gas burning, heats up the air in the balloon. As Hot air rises above cooler air the balloon takes off.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
The longest someone has flown in the air is 50 hours!
it took about a year for the first hot air balloon to be made.
If you have children, it should be illegal to have a balloon ready to jump into and take off.
I wish I knew

yes

As long as they have flue to heat the balloon.
to fly that far in a hot air balloon it would take up to at least over 15-30 days but that also depends on how fast you get the hot air balloon to fly and if you stay straight on course
Balloon will not fill up the full bottle in this experiment as the air is restricted by the walls of the balloon. Balloon is a solid so the air will take its shape.
Depends on the size but typically ten to twenty minutes
100 hours
