I am bit confused with the Phasor representation of voltages and currents. Does the magnitude of the phasor length is RMS value or Peak value? Please advise.
Phasor is not a rotating vector, it's a static vector representing a sine quantity. Scaling of vector length is a matter of convention. In power electronics we prefer rms, as used in the linked tutorial.
I am sorry i did not understand when you said it is not a rotating vector. Does it make any difference? Can I use the RMS values for both rotating vector and static vector? And also how do i know if i am using RMS value or Peak value, do i need to indicate in the representation? I know static vector is called the phasor, does rotating is also called phasor or by another name? Please advise.

The length of a rotating vector corresponds obviously to a peak value. For the time invariant phasor constant, both rms and peak is used, depending on the application range. If there's a risk of ambiguity, you should declare your usage. In some literature, the rotating vector is also called phasor, hence the requested clarification can't be made.
