Yes: Try hydrogen - it worked for the Hindenburg
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
One way to blow up a balloon without blowing into it is to use a hand pump to inflate the balloon with air. Another method is to use a helium tank and nozzle to fill the balloon with helium gas, which will make it float.
Helium is a lighter element compared to air, helium also has fewer molecules than air.
Helium is lighter than air. So helium balloon rises in air.

Helium gas is lighter than air and hence balloons filled with helium will float in air.

A hot air balloon doesn't contain helium.
No. Helium is lighter than air

Helium is lighter than air. hence helium balloon will float in air.
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
