As far as Blue is concerned, she is, imo, the head fairy. Just her position in SB as "Mother Superior" indicates that she has the leadership. While the curse turned all the fairies into Nuns, it kept some kind of order within the ranks, and Blue is set at the "top dog" if you will.

She was the spokesperson from Fairies to the War Council of David and Snow, so that would seem to further imply that she was in charge at that point. (Just as Grumpy seems to be in charge of at least his small contingent of dwarves).

Now, whether she was in charge back when Rumple first came to power is anyone's guess. She was definitely powerful enough not to fear encountering the Dark One. And at some point she banished the Black Fairy (Still awaiting confirmation whether this is Maleficent, or if there is yet another storyline), That may have been the point that she claimed the top position.
