Dear Tejas,
I agree with your intrepretation of all of the modes except for the 1st blade edge (collective), which I would interpret as 1.706 Hz, and the 2nd blade flap (collective), which I would interpret as 3.784 Hz. Please see my May 16, 2011 post in the forum topic found here for a description on how the MBC3 script changes the mode descriptions for the blades (from individual blades to collective/cosine/sine): Eigenanalysis FAST.
Best regards,
