Yep, need more info on exactly what you are trying to do. Do you want each to run independently, all starting at the same time, or do you have lines that are dependant on others to be finished before they should kick off?
Sometimes its better to make a couple of batch files to group like tasks that can run cuncurrently, then call each one from a "master" batch file that starts automatically at startup.
But you can also put it all in one batch file.
