Normally from some type of injury, like dropping a heavy object on it, or frequent running causing constant pressure on the toenails. If it is not caused by an injury, it is more than likely a fungus, and you can get a prescription treatment from your doctor to take care of it. Fungi are very difficult to treat and can take several months, and over the counter medications are rarely helpful in toenail fungus.
It's not.

Not much. Keep the area clean to minimize risk of infection and wait for the new nail to grow back; that is if you didn't damage the nail matrix during whatever event that caused you to lose your nail in the first place.
Regularly trim toenails straight across, avoid cutting them too short, wear properly fitting shoes, keep feet clean and dry, and moisturize regularly to prevent thickening of toenails. If thick toenails persist, consult a healthcare professional for further evaluation and treatment options.
Make sure they don't fall off.
your feet are not able to fall off because they are connected to your body.
