the air contain many layers. the oxygen having more density
than carbon-di-oxide, hydrogen, nitrogen, etc., so when we
lighting the fire it produces carbon-di-oxide, as mentioned
above this is weight less than oxygen, so it tends to go
above the oxygen layer., thatswhy it goes in upward
direction...

First you must go back to simple chemistry.
What is a fire? It is the combustion of carbon.
Carbon is being oxidised to form carbon dioxide.
This is exothermic, meaning what? It gives off ENERGY.
With A level Physics you learn that an atom with electrons
which has been excited will emit light photons, this is the
visable fire.
The rest of the energy is lost as heat, which will make the
carbon dioxide less dense as anything heated expands and
has a lower density. This lower density causes it to rise.
This is the ONLY reason a fire rises upwards. Ignore the
rubbish above, it isn't correct in the chemical or physical
processes.
