Iccha has that about-to-speak-but-you-stopped-me kinda look a lot with her mouth open
Taps has that girlie grin and girlie giggle
Taps also has uses her thumb and finger to make that chutki sound when she is angry
Rathod has that supercilious look or the frown
Divya has that arrogant look
Mai has the irritated look
Daddaji has the angry look
Nani has the evil gap-toothed look..or that overly indulgent ingratiating look with tappu or when she wants something
Rohini has the blank look
Pushkar has the slimy look...
just my opinions...would love to see your faves
