Hello Sujit.

If you intend to use all the nut runners at the same time, and continuously, then yes, you need to have a compressor that has the capacity to supply that total volume.

Each HP of electric motor generates about 4 CFM of compressed air at 90 PSI.

You may also want to read the pages on this site that are linked from the "Sizing" navigation bar button.
