You need to run the 'scanimage' commands in the background.

For Example:

  scanimage -d $dev1 --format pnm > scan-dev1.pnm &
  scanimage -d $dev2 --format pnm > scan-dev2.pnm &
  scanimage -d $dev3 --format pnm > scan-dev3.pnm &
  scanimage -d $dev4 --format pnm > scan-dev4.pnm &
  wait

If your scanners are on different hosts then you can run saned to
allow a central point to start all scans, still in the background,
and wait for them all to finish.
