No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.
Hydrogen, carbon, and oxygen
NO ... all burning/combustion reactions are exothermic.
For any combustion reaction O2 is required .
No, it means that the fire can start all by itself.

It can. I heard a terrible story: a group of Boy Scouts decided to do a service project and refinished all the woodwork in the church that sponsored their troop. They used mineral spirits-soaked cloths, and left a pile of them in the church. Spontaneous combustion happened and destroyed the church.

Pour petrol on you and light a match KAPOFF!
Mulch, compost, and decomposition all generate intense heat and a risk of fire. The larger the pile, the more fuel and insulation is available to feed potential combustion. Larger piles also make it more difficult to extinguish a burning mountain of mulch. Mulch that is piled up more than a few inches deep starts to heat up as it decomposes, which can lead to fires starting via spontaneous combustion.
CO2 (carbon dioxide) is a naturally occurring process required for plants and animals to live. CO is carbon monoxide and can be the result of oxygen starves combustion, forest fires, and internal combustion engines. Both can be deadly.
All nuclear decay is spontaneous.
Hydrogen, carbon, and oxygen
We use it for breathing; we can't live without it. It is also an essential component of all sorts of fires, including internal combustion engines. It's all around us. we can't not use it.

Yes. All gas furnaces will have products of combustion.
