I don't think it's a leaf tip - there is no ridge in the center of the ruffle. I think it's something like # 150 but in a larger version?
To get the look start on the far side top of the cupcake and make a row of zigzag piping but instead of going from side to side, move your hand up & down; then it's more rows across the top of the cc until you cover the whole top - only 3 or 4 rows really. You are holding the opening of the tip straight up & down (verticle/like a slot) not side-to-side (horrizonal/flat).
The pink icing swirl could also be a tip 150 or any smallish rose tip but instead of turning the hand w/the bag you hold your hand still and turn/spin the cupcake. On this one I'd start in the middle of the cupcake and circle ever widening layers around.
There is/was a drop flower tip that can do similar but as I remember it's small; I've log ago forgotten the #
.
