As Emiluvsmusic said Shunsuke could only be a guy's name and you pronounce Shun like 'put'. I can't really come up with a good example
Oh, and about the girls names you posted earlier (1)~(5).. well Shinko, which is (1), isn't really a Japanese name. It does sound like it but hm, I doubt that any Japanese girl has it as her name. The others sound right, though. What about Shion or Shiori? Those are some names I came up with for a Japanese girl's name
