Let Say we take 1 mole of glucose/Sucrose, then heat it up to 800 degree Celsius,
Case-1 (Inert 95%Ar-5%H2 atmosphere)
Case-2 (Air atmosphere)
Case-3 (N2 atmosphere)
then what reactions will happen in all those cases,
and what will be the carbon content we will get in the final product in each case.

welcome,
it is customary to at least try yourself before asking,
you will find folk here very helpfull,
but if you can't be bothered to try yourself, why would others ?
so, have a try, reply with your best answers and you will probably get more help.

I wouldn't expect you to try that for yourself. Few people have all those gasses and a reaction chamber capable of 800C on hand.
It appears to be a question for pedagogical purposes rather than mere musing on your part. So perhaps a bit of advice will aid you in arriving at a
hypothesis.
Consider how the 3 gas mixtures vary in their reactivity. Are they inert? Or oxidizing? Or reducing in nature?
Posit to yourself what reactions may be possible with sugar in each atmosphere at high temperatures.
Check to see if these reactions will occur at the temperature in question.
Finally, check to see if the products you think you'll get will further react with the atmosphere in question at those high temperatures.

Chironex is the go-to on this: their interest is in hydrothermal formation of carbon allotropes.
This thread might appeal: http://www.sciencemadness.org/talk/viewthread.php?tid=70699#...
in it somewhere is discussed the thin layer of graphene oxide that forms in a hydrothermal reactor when sucrose is subject to decomposition at 160
degrees in a closed vessel.
Check out the sealed pipe in the oven method!
