Bubble wrap is made by sealing two layers of plastic together with small pockets of air trapped inside. These air pockets are what give bubble wrap its protective cushioning properties.
Yes!
The bubble in the egg is called an air sac, and helps prevent the egg from drying out (too quickly).
If you are asking about a bubble in a liquid, the answer is that the bubble has lower density (the gas inside is "lighter") than the surrounding liquid. If you are asking about a soap bubble, the answer is that air currents carry the bubble up. The bubble itself is not lighter than air (unless filled with another gas) but the film making the bubble is so thin and light that air currents can move it easily.

Only the BelAir had the bubble top and there were a total of 166,000 produced. Only 15,019 had the 409 engine. As to the exact number that were bubble top cars I am unable to get an answer I would be 100% sure of.
When an air bubble is released underwater, it will rise to the surface due to buoyancy. Buoyancy is the upward force exerted by a liquid on an object immersed in it. As the air bubble rises, the water pressure decreases and the bubble expands in size until it reaches the surface.
Soap bubbles have properties that allow them to trap and reflect light, which can influence air temperature. When exposed to sunlight, the soap film of the bubble can absorb heat, causing the air inside the bubble to warm up. Conversely, at nighttime, the soap film can radiate heat outwards, potentially cooling the air inside the bubble.
