I agree with Alan that the top one is most probably Nawa Sari. I assume Alan wants to see the grain sheaf in the hand behind the back, but everything else about this hilt fits the commonly encountered design for Nawa Sari.
The hilt with the hair over the face probably doesn't represent a single figure, but i seem to recall story of leyak or ghosts that are know to appear in this form, so that is the direction i would investigate with that.
No idea on the really abstract one, but i do find it to be really cool.
