You can use a trigger_multiple or an info_volume. Once you need to check, loop through all players, and for each test if he IsTouching(object), in which case you want to count him.
i think you know how to include scripts if not just put this line after zombiemode in your map.gsc and then make the file in maps folder with the name of remember that it need the gsc extension this code just gets how many players are touching a trigger multiple and then print the number in game also, in radiant make a trigger>multiple with the "targetname" "multiple" and sorround with the trigger the area that you want to know the number of players inside
