Even if you set profiles to run all at the same time, they will run sequentially - one after another.
You cannot control the sequence in which the profiles are run. The only way to control which profile runs first would be to set each of the profiles to run at a specific time, or by using the Run Programs Before/After feature of Second Copy.
For example: If you want to run Profile-1 first, then Profile-2, and then Profile-3, then you can set Profile-2 to run in the "Run Programs After" section of Profile-1, and select "Wait for program before proceeding" box. Then in the Profile-2 profile's Run Programs After section, enter Profile-3 profile to run, and select "Wait for program before proceeding" box. For more information on running programs before and after, please refer to the Help file.
