Top left is a narrow hem foot, top middle is an adjustable zip/piping foot, top right is for attaching bias binding.
Bottom left looks like a quilting foot, the two in the middle look like they might be for hemming again just different widths and the bottom right is used for flat stitching one fabric to another for instance inserting a lace into a fabric
