Not quite there.

Stagnation points are the places where the airflow stops. That's where the stagnation temperature is reached.

Where?

A point on the nose;
A line down the leading edge of each flying surface;
A line round the intake lip of each engine;
(In the case of the second and third, only if the leading edges are perpendicular to the local airflow) for example.

And, yes, elsewhere there is a lesser but variable amount of kinetic heating.

How much heating? Rule of thumb, stagnation temperature increase above ambient in Celcius is TAS(knots)squared/100
example: 500 kt TAS, increase 25 deg C.
