Twenty (20) pages of google results and I still can’t find the names of the other two passengers. Weird. Media is always all over these crashes to be first with the names so they can ask the relatives, “how they feel”.
IIRC from one of the many articles I've read on this, one of the passengers was the pilot's son. Perhaps they don't release his name because he wasn't a paid passenger on the manifest. The second passenger without a name may be a friend of the pilot's son. Just a guess, but it might fit the scenario.
