Jasper/Peridot/Lapis Lazuli
Yellow Diamond seems to hold some sort of authority, as Jasper and Peridot needed to report to her. As they seem to obey her, Lapis Lazuli and Peridot feared her name.

In "Cry for Help", Peridot sent out a distress signal using the Communication Hub in hope that Yellow Diamond would send help.
