This is somewhat an educated guess, but it seems to me that you want to start the (in this example) three programs in a row without stopping/hanging/waiting for each to complete, just like the Linux command suffix & in startProgram &.
To achieve this, you could use the approach of this SuperUser answer. It simply states that you can use the start /B prefix before your commands.
So, after applying this fix, your batch file could look like this:
start /B G:\KarenPwrTool\Replicator\PTReplicator.exe
start /B G:\FileManagers\VfileViewer\v.exe F:\alk
start /B G:\FileManagers\VfileViewer\v.exe G:
If you need the output, use the redirect solution from the end of the answer.
