I have a mesured voltage and current. I want to find the impedance magnitude, real and imaginary part then plot yquist and cole-cole plot, but i don't know to proceed, can someone help please.

By convention, the real part is the voltage, and the imaginary part is the current. Thje phase is the angle between them.
Ohm’s law states
so
At least that is how I understand it.
Also
where X is the reactance (either capacitive or inductive).
Calculating those would be relatively straightforward with your data.
