who are they ?

This is a quiz for Singapore Cantonese Opera fans. I think it is not hard. Answers will be given in the second post after this.

I was looking through some photos I took at opera shows. A few are not clear (for example, the first photo below) but the blurriness makes them suitable for quizzes. I don't think I have posted these photos before. All are Singapore artistes.

Who are these two?


Who is this huadan?


Who is the sheng?
