吉興 JiXing ( = YenJiXing 顏吉興, maker, based in 汕頭 Swatow/Shantou )
點銅 DianTong ( Although "Tong" alone means "copper", this term actually means "pewter"; some items made by JixXing are marked also in English so it's clear)
Picture 2: 正銀白 ZhengYinBai Although the word "Yin" indeed means "silver", I found an article in Mandarin showing the same mark and it indicates that the material is "white copper".
