Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
because it helps it fly in air
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Hydrogen gas was used in air balloons because it is much less dense than air and therefore rises, taking the balloon with it. it is unfortunately also very explosive so not used often anymore.

Hydrogen is too flammable
Hydrogen is used in weather balloons because they are very light which help the balloon to float or fly easily.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Helium is used instead of hydrogen because it is nonflammable.

Hydrogen was one of the earliest gases to be used for inflatable flying balloons, but following the Hindenberg disaster helium is now used, as it is chemically inert.
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.

Although you can, it can be extremely dangerous, so certainly is not recommended.. In some jurisdictions, it can be illegal, depending upon how it is being used.
