As I said above, this depends on how you measure the rate of those other
clocks.
Scenario 1. C2 runs [...]

Read what I wrote above. You CANNOT state "C2 runs ...", you must state
WHO is measuring its rate, and HOW they are measuring it.
C1 rotates in the same direction as clock C2. I said C1 is MY CLOCK.
I am traveling around the circle with C1. I said I MEASURE the rate
C2 is running by looking at the received frequency from a laser at C2
I MEASURE when the beam arrives at C1. It never changes.

The statement "Clock C2 runs at such-and-such a rate" normally applies
to the clock ITSELF. In SR all clocks run at their usual rates in their
own rest frames, so such statements have little or no meaning.
