Any time you are simulating continuous tone with solid ink colors, I'd call
it halftone.

Sure to both.

For that particular halftone it sounds like it.

I don't believe that only stochastic methods vary the frequency...
Stochastic only means "involving chance or probability", as in random.  You
can vary the frequency, and not be random...it can be very deterministic
(opposite of random).
