I would call the first coin to be 1 Mon Shin Kanei Tsuho, Ishinomaki-sen. Which makes it dated most likely in Kyoho 13 (1728).
Also agree with Finn235 - the other two coins look to me more like original Chinese Northern Song coins: Xiang Fu Yuan Bao (1008-1016) and Shao Sheng Yuan Bao (1094-1097). More likely then their corresponding Vietnamese and Japanese Nagasaki trade coin imitations
