The third one may be signifying an action as well... Like call or yell.
From my first guess the 1st 3rd and 4th have been confirmed incorrect so I was close on the 2nd picture which I guessed as Piper, Holly Comb, or Charmed...
Pay/Take/Give - Piper - Calls/Yells - Tuning
My guess can only be: He who pays the Piper calls the tune.
Did I get it right High?
