If by light you meant a heat lamp then yes they do. They would need a heat lamp until they are fully feathered.
having hatched numerous chicks i can say that all chicks are not yellow. in my experience the yellow chicks become white or pale coloured hens, i have hatched grey chicks, brown chicks & black chicks
The only thing the light is used for is heat which is what red light is. All other colours of light is only an irritant to the chicks so steps are taken to eliminate them.
Usually 24 hours but it is always best to leave them all together until all the chicks have hatched. The chicks need time to dry and fluff up. When they first emerge from the shell they are wet and weak, subject to cold temperature drops. You need not worry about food and water for 36 hours since they still have some reserves from the yolk they developed from. When moving them from the incubator to the brooder box, make sure the temperature is close to the temperature of the incubator, in the high 90's directly under the lamp. There should also be room in the brooder box for them to get out of the heat is they wish.
Many chicks never know their mother. Most chicks are artificially incubated and are raised in a brooder with other chicks their own age. Chicks hatched by a broody hen in the chicken coop often stay with "mom" until they are full grown at the age of 6 to 8 months old and will often stay with "mom" all their lives. This is basically just for companionship as the mother hen does not feed her chicks, they are born knowing how and what to eat.
No. all chicks do not start out yellow. The chicks you see in advertising pictures and in magazines are photographed more often for a number of reasons. The yellow balls of fluff are cuter than a mottled brown/ white or all black chick. More distinguishable as the "chick" the general public expects to see. The majority of chicks hatched in spring (Easter) by hatcheries are of a certain breed (a cross between a Plymouth rock and a leghorn) and usually used for meat production. A bit ironic that the advertising media has chosen the cute photogenic chick with the shortest lifespan for an icon.
Live shipping of day old chicks is done all the time. For up to 72 hours after they hatch the chicks are still ingesting their yolk sacs. This provides them all the nourishment they need. Chicks do not require food or even water for this period in their lives and survive quite well. Heat is the usual problem. Most hatcheries will only ship in batches as the more chicks shipped the greater the body heat provided.
you need to take the chicks away it wont be long before the mama takes the ducklings into water and the chicks will not survive
You should have food out all the time for your baby chicks.

can bay chicks use sunlight? yes although the sun is not there all the time. but you can use a lightbulb at night when the sun goes
They need a mother until they grow feathers which might be in about a week, then you can let the mother be a normal hen again, but separate chicks from all birds
They probably want to sell you something.

It would waste electricity if the light were on all the time. It only needs to be on when the door is open.
It depends on the species. In some penguins adults are present with the chicks at all times until the chicks fledge but in some species, the chicks are on their own for hours at a time if not longer while the parents go out to sea to fish.
The chicks should all stay in the incubator until the hatch is complete and the chicks are fluffy and dry. They should all be moved to the brooder box at the same time. The chicks will roll the peeping eggs and that is ok. Sometimes the movement of the completed chicks will get the emerging chicks to begin and that is a good thing. Do not be hasty in removing the newly hatched chicks from the incubator, they can and should remain in there for up to 24 hrs.
There is insufficient information in the question to properly answer it. You need to specify which light and which aeroplane. Please restate the question.
