Who is Terrence Fok, & 2 of him ? Fok Shui Wa and Fok Ta

[STSH]

There are two people listed as Terrence Fok. This seems a bit odd.
Does anyone have evidence that these two guys both have the English name Terrence :

Fok Shui Wa

Fok Tat Wa

Also, what do these guys look like ? I have recently watched a string of films featuring Fok Shui Wa in the cast, and I am still unable to work out who he is.
