Nice little assortment. The second one is a bit worn and suffers from poor contrast lighting in your pictures, so I can’t reliably identify it. The others are all ‘cash’ coins from the Qing Dynasty of China. Note that Chinese Emperor names get various degrees of ‘anglicisation’ and that Emperors had a reign title, a temple name and a posthumous name, so you’ll see various alternatives depending on individual reference sources.
The first one is Shunzhi Emperor (also Shih Tsu or Shizu) and from between 1644-1661. It’s the 4th series of his coinage, so from the later part of his reign. The reverse Chinese/manchurain characters for “Boo Ciowan” (Board of Revenue mint, Beijing) and “Pao-Ch'uan” (The Fountain head of the Currency).
The third one is Daoguang Emperor (also Hsuan Tsung or Xuanzong) from between 1821-1850. Also Board of Revenue mint.
The last one is a higher denomination, I think 10 cash. It’s Guangxu Emperor (also Dezong) who ruled between 1875-1908, but looks to be from between 1903-1905. Like this one:

Sadly, none of them have high collector value in a monetary sense, but you did OK at two dollars.
