The thing that looks like a walking foot is a zigzagger.
It moves the fabric back and forth for each stitch to make the zigzag.
I don't know what the plastic thing is. Middle top looks like some kind of combination straight stitch/zipper foot. Top right is an adjustable hemmer. Not entirely sure what bottom middle is....a button foot? For sure not sure what the aluminum/nickle thing is...some kind of a securing joint plate?
