I tell what little I think I can ascertain. The first coin id Ching dynasty, just prior to the formation of the Republic of China in 1911. The second (half coin) appears to be a Republic of China coin issued for military use, date -1913.
The first half-coin picture shows the date "Year 2". Although most of the regime portion of the date is missing I think lonegunlawyer is correct in attributing the coin to the Chinese Republic, of which Year 2 is 1913. I think the small item is a token/charm, not a coin. The Arabic coin is dated AH1293, and has a 2 under the toughra, so I'm guessing that it was issued in 1877, the second year of someone's reign. The design hints at Turkey, or possibly Egypt. If it is about 19mm and 2.8g, it might be an Egyptian 2 qirsh (KM#293) for which there is a very low quality picture in my decade-old 19th Century Krause.
1/2 coin is from szechuan. Small coins are from Travancore, India. Last coin is from Egypt, 2 Girsh dated 1293/30--1904.
