No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.

The air inside a balloon is less dense than the air around it. When the balloon is inflated, it contains less air molecules compared to the same volume of air outside the balloon, making it less dense.
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.
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.
When heated air is trapped inside the balloon, it becomes less dense than the surrounding air. Since hot air is less dense, it creates a buoyant force that causes the balloon to rise. This is because the hotter air inside the balloon is lighter than the cooler air outside, creating a pressure difference that results in upward movement.

When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.

Fire contacting with the air inside the balloon. The heated air within the balloon is less dense than the ambient air surrounding it, therefore for the given volume it is lighter and so rises.
The pressure of the air outside the balloon decreases as it goes higher in altitude because the air becomes less dense at higher altitudes. This decrease in pressure causes the balloon to expand as the air inside the balloon pushes outward.
