All except a couple of bandits and hotel workers
Ok, let's start
The hottest ID of the spring
This guy
is the same guy from "New debt collectors" 
and "Final edge" 
There is an unidentified actor in "Final edge" - Yau Ming (3)
In "Super cop" there is an unidentified actor with the same chinese name - Qiu Ming (2) (his name doesn't appear in credits, and I don't know who added him)
So I suggest to merge both actors.
I'll check another Yau Ming's (3) movie - "Killing skill" for the complete ID of the guy.
This dudette
is the same actress from "New debt collectors" 
There is a unidentified name in "New debt collectors" - Wong Yim-Ting
There is an unidentified name in "Super cop" which chinese spelling looks almost the same - Huang Yan-Ting(again, the name does not appear in credits, and I don't know who added it)
So I suggest to merge the names.
Facebook search shows that Huang Yan Ting is mostly a girl's name, so the owner of the name is probably the actress on the photos above.
This guy
is the same guy from "New debt collectors"
is the same guy from "Spy gear" 
, "Millennium dragon" 
and "Angel on fire" (1995) 
and his role is Ah Ming.
