The pair probably are "entertainers" seated at the side waiting for their turn to perform. Note the following:
01. This Jade performer is perhaps a young girl with the wide-eyed and naive facial expressions and the male may be the male relative.
02.The dress is long sleeved with a front V tucked in.
03.Again there is a hole bored from top to bottom.
04.The hairstyle of two pigtails pulled to the back again emphasises a young person .
These Jades although not Nephrite but pseudo Jades are nevertheless important extant evidence of Ancient China customs and lifestyles.
