Most of those feet are meant to work with a different attaching system than Singer. Singer uses side clamping feet (and occasionally back clamping) and these are mostly rotory clamping feet, also called top clamping feet or rotory feet. Many manufacturers used this system with slight variations on where the needle hole is, etc. so I'm afraid I couldn't tell you just by looking at them what machines these would go with.
But! Rest assured, you aren't crazy:except perhaps the small foot in the upper left of the picture, these feet simply don't fit your machine!
