Ok the first 2 should be retired immediately, the kwai mai pink has the wrong variety pictured. There are some rebadged standards with different names. Not sure the haak ip is the real deal also. Emperor looks like a small fai zee siu maybe an early selection. No sum yee hong or other good ones from more recent decades. Looks like not much new has happened for 50 years of so. Look at the link from 40 years ago in my local area to figure out some correct names.
