Because the eggs hatch into a larvae, called a naiad, that lives in water.
Because the larva stage of some insects have gills instead of lungs. For example the mosquito. It's larva has simple gills to absorb oxygen through the water, when it moults into an adult, its body tissues are re-arranged, and it develops lungs to breathe air.

Great diving beetles have the ability to dive under water in order to hunt for small fish. Prior to diving, they store a supply of air bubbles in their wing cases and use them to breathe while under water.

Lady bugs can fly unless they are injured or deformed. They fly so they can get to their food aphids which live on plants.
While you could try, it is not recommended. If you attempt to take a Beetle underwater without specialised modifications, the car will most likely be unable to function because cars do not have gills.
damselfly nymph because it has a streamline body
Possibly but river animals usually manage to find sheltered backwaters when the water starts to rise.
In the water. Why are these questions so dumb?
