If a balloon that was blown up at a low altitude is brought to a high altitude, it is likely to expand and potentially burst. This occurs because the atmospheric pressure decreases with altitude, causing the gas inside the balloon to exert more pressure on the inner walls as it expands. Since the balloon material can only stretch to a certain limit, the reduced external pressure allows the internal pressure to increase, leading to expansion and possible rupture.
The balloon would expand as it rises in altitude due to the decrease in air pressure. If it expands too much, it may pop or burst because the external pressure is lower than the internal pressure from the air inside the balloon.
If a balloon is placed above boiling water, the heat from the water will cause the air inside the balloon to expand. The balloon will likely inflate and may eventually burst if the heat is not removed or the balloon is not released.
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.

On modern airplanes no, because the cabin is pressurised to the same atmospheric pressure as on the ground. If the balloon was on the outside of the plane, and the atmospheric pressure at that altitude were low enough, then yes, the balloon would pop.

If you swallow a balloon you will most likely suffocate and die. This may sound a little over the top however it is likely that the balloon will wrap itself round your lungs and will disrupt your respiratory system. On the other hand, a balloon might block one of your vital arteries or might get stuck in your throat. If you swallow a balloon you should call an ambulance immediately.

the balloon's volume would decrease!!!
They would likely pop it very quickly. The problem with that is that little pieces of the latex from the balloon can be projected or torn away and there is a choking hazard. It is not recommended for that reason.
If you prick the balloon more, it is likely to burst and deflate rapidly as the increased number of holes will cause air to escape quicker. The balloon will lose its ability to hold air and will eventually become completely flat.
The velocity of a balloon is most likely caused by the difference in pressure between the inside and outside of the balloon. As the air inside the balloon is at a higher pressure than the surrounding air, it creates a force that propels the balloon in the direction of lower pressure. This is known as the principle of buoyancy.
A balloon filled with helium will likely deflate faster than a balloon filled with air because helium molecules are smaller and can escape through the balloon material more easily.
Altitude sickness most likely
Most likely it is Helium gas.
Balloons may stick to a knit sweater, but normally the electromagnetic force will oppose it. However, once a balloon is rubbed on a sweater, it can stick to a wall (or other surface) by creating an electrostatic (magnetic) field with the stationary wall.
If you prick a balloon without water, the air inside the balloon will escape rapidly through the hole created by the prick. The balloon will quickly deflate and likely make a popping sound.
