I am suggesting that the gentleman on the right is Bob Nunes. He is credited and has dialogue but very little is known about him. There seems to be no other pictures to compare him with and he has only 1 other credit on the IMDB, which may not be accurate. The lady virtually covering her face is Olga Andre. She also has very few credits in film.
