How to measure he CMRR, offset current, bias current and offset voltage of AD8561 Comparator? Can you elaborate on the test circuits and test methods to test these parameters.?

You will have to add circuitry to make the circuit stable. (Comparators are not unity gain stable)
But that wiil get you started.
