There are two (2) exits after clearing Customs for international arrivals. This map may help:

On level 2, international arriving passengers can exit from either "B", at/near door #6 or "C", at/near door #9. Which one depends on the baggage carousel their flight used, usually.

This area, in light blue on the map, from at/near door #4 to door #10 is only accessible to airport pass-holders. This was done to keep the area clear and allow arriving passengers to exit. When the airport first opened this area was open to all, and it became quite congested, making it nearly impossible to get through the crush. Hence the convoluted escalator/travellator flow, and the elevator (on that side) not stopping on level 2.
If you want to meet/greet someone it is best to wait at/near the official meeting point/area near door #3, or perhaps on level 3 if you've used the parking garage, or level 1 if you'll be using a taxi. Just choose a door # and level to meet.
