Far left I believe is a cash coin using the seal script writing style. This would be older than the Qing dynasty (1644-1908). My guess is Song dynasty (ca. 900-1100), but I would have to search for a bit to be sure. Song dynasty coins were frequently made of iron... is this one magnetic? It certainly looks to have spots of rust.
Middle one I have never seen before.
Last one I agree is a charm.
