The one on the top left looks like the Edge Stitcher from my Featherweight. "This useful attachment is fastened to the machine in place of the presser foot, and will be found an indispensable aid whenever stitching must be kept accurately on the extreme edge of a piece of material."

You can sew lace or ribbon together (straight edged lace), make piping, apply bias folds, stitch a wide hem, make a french seam and do tucking. Quite the wonder foot!

The one on the left is an edge stitcher and the others are rolled hem feet. I have picked up several boxes of them at antique stores. I bought an adaptor for my Bernina that lets it accept low shank feet and use mine all of the time.
