I'm sorry to say I can't help much on this round. I think that first object is something to do with a belt--taking up slack in a loop. I don't know what they are called. The other two objects seem to both be shown from the back side. Maybe if you posted some pics from the front. I expect someone will chime in with a correct answer very soon and my guess will be wrong! But, who cares? We are all in this together. We will all know very soon what you are holding in your hand.
