It really depends on the person. A person with a high percentage of body fat may survive up to two weeks. It sounds amazing but its true the human body is amazing. After a long enough time your body will shut down all but the most vital actions such as keeping your heart beating etc. Water is a whole different story though. You wouldnt last more than maybe 3 days tops regardless of body fat.

Really depends upon the person and how fast their metabolism is. Humans cannot survive more than two weeks without water, however, there have been people known to survive 56 days without food.
Hope this helps

Quite a long time actually. You can digest yourself (first the fat, then the muscles) to a freakish point. I think the record is actually more than a month.
You can last a few days without water (1 week in good conditions)
However, you cannot survive more than 3 days or so without any sleep without going mad

NOT LONG. U NEED FOOD TO CREATE ENERGY.
FOOD = GLUCOSE
GLUCOSE + OXYGEN = ENERGY + WATER
