To change the vehicle, edit the 9th line, which is 'vehicle name'. The following line is its variant.
To change the occupants, simply scroll down a few lines and you will see 'driver' and 'passanger 1'. You can add more passengers, depening on how many the vehicle allows you to.
For the vehicle names and ped names you will have to look around these forums. If you search for 'vehicle variant lookup' you will find a list with the internal names of the vehicles for Saints Row The Third. Quite some vehicles from 3 made it into 4 so it is handy.
To change the cop to a SWAT unit, replace npc_cop with npc_cop_SWAT01_mw
