I have vibration data in which I have magnitude,phase and frequency rows. Then how to take FFT of this vibration data?? Do I need to add magnitude,phase and frequency??

If you already have the frequency, magnitude, and phase data, you have the Fourier transform of your original time-domain data. Nothing else is required. To plot it, just plot magnitude as a function of frequency, and phase as a function of frequency. See the documentation on subplot for details on doing that in one figure window.
