Combustion (fire or burning) is arguably the most common example of converting chemical energy into thermal energy. But consider that all animals create a bit of thermal energy converting chemical energy into heat (as well as some mechanical energy) when they move.
In saying what the overall efficiency would be, I suppose you mean for other processes, creating the chemical energy for example, and using the thermal energy. This is impossible to answer, not knowing what these processes are.
No. An oven is an example of thermal energy.
from what i can find, it is only possible fro chemical energy to be transfered to thermal energy. burning wood is one example of this.
when gunpowder is ignited
chemical energy in batteries to thermal energy.

I think the answer is a No because if you change electrical energy to thermal energy to an example it will mix into chemical energy.
when gunpowder is ignited
For example thermal energy.
When you burn a fuel in air you are converting chemical potential energy into thermal energy. The only energy input needed is to raise the fuel temperature to the ignition point. To obtain electromagnetic energy you have to drive a generator, which requires mechanical energy, so you have to use the thermal energy to drive a heat engine, a gas turbine is a good example.
A car engine, a coal or petroleum power plant, a nuclear reactor.
Example is ,an electrical heater connected to a main switch and the heater is placed in a bucket filled with water.
neither, Law of conservation of energy in a nutshell: energy cant be created or destroyed. Energy can be converted nothing else. IE: when you burn a candle you are CONVERTING the chemical energy stored in the candle into thermal energy.
