it is not good for them to.if it is a pet and you have a tank/habitat for them to live in put a little pond like thing that doesnt cover the whole habitat/tank so they can have land to sleep on which is what they usually do.it is possible for them to drown while sleeping in water a whole night:)
No, they are poor swimmers, and will drown. If forced to stay in shallow water, they will develop skin infections, just as you would.

If your turtle is a water turtle it should.
Turtles, like any other animal, sleep when they need to. I catch my four napping on a regular basis. They love catching a snooze while out sunning themselves. They can't sleep under water they have to be basking. If they were to sleep under water they might drown. My turtle spent her first night completely undewater (sleeping) So I guess they do sleep underwater they hold their breath for hours
They can sleep under water because they can hold their breath for a very long time.
[Improve]The loggerhead sea turtle slowly moves by their fins. When they move, they slowly press their fins against the water. This makes a power source which causes them to move along. Please save the loggerhead sea turtles from extinction!
Yes, whenever you are traveling with a turtle, you should put it in a container that contains water.
water
No. the ammonia levels for fish water are different than in turtle water and are meant for larger quantities of moving water. To suit the habitat need of a turtle yo should find the correct turtle treatment.

Yes salt water crocodile sleep. The sleep with most of their body submerge neutrally buoyant in the water. Salt water crocs are also very stealthy hunters.
