need help with a few items

[edlynne]

Found these items and not sure about any of them. Left to right. The first looks like a cross and appears to have a gold color where it has been scrapped. The second has two knobs on the backside. The third has a flower pattern on the front. The last has the name W.E. Peterson on the front with some other writing. One the bottom are a pair of earrings found in the same hole. No marks on the earrings, just wondering if anyone has seen others like them. Thanks
