It is just air, only at slightly higher pressure.
the air inside the balloon has more kinetic energy
No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.
No. Air or helium goes inside the balloon.
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.

The hot air inside the balloon expands, making the hot air balloon fly.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
No, the inside is a gas (air).
Because the air is coming inside the balloon.
