That's a lot more than five devices.

I hate to throw RTFM at you, but from "man sar":

  When data is displayed, the device specification dev m-n is generally 
  used ( DEV column).  m is the major number of the device, whereas n is
  a distinctive number.

So, the dev identifiers you're seeing are definitely the major/minor
numbers of the disk devices.
