I don't think any star has sufficient heat and pressure to effect nuclear fusion in its atmosphere. There are very high temperatures there, to be sure, but not high enough for fusion, I'm afraid. Also the atmosphere of stars is quite tenuous, which would act against the necessary conditions for fusion.

No, because nuclear fusion requires temperatures of over 10 million degrees Celsius. It also requires extremely high pressure to "melt" the atoms and fuse them together.
Atmospheric temperatures on the Sun's atmosphere are between 100000 degrees Celsius and 1 million degrees Celsius. And the atmosphere is not dense enough for nuclear fusion to happen.

No, because the pressure and temperature is too low. It takes place in the core or sometimes a deep layer just outside the core.

You need much hotter temperatures than what the Sun has in its atmosphere, as well as much higher pressure
