Chinese cash coins, real or fake? Identifying help needed as well.

Here are some Chinese coins I recently acquired. I took a stab at identifying them, but would appreciate a more expert opinion. Also, I have no idea if any of these are fakes.

From right to left across the top, I came up with:
1. FD# 2388 (actual diameter 25mm)
2. FD# 2508 (actual diameter 25mm)
3. FD# 2397 (actual diameter 20mm)
4. FD# 2344 (actual diameter 26mm)
The three in the center row I called FD# 2323 (actual diameter 23mm)
The five at the bottom, FD# 2297,2314 (actual diameter 24mm)

The diameters didn't match as well as the pictures in some cases, so these were my best guesses.

Thanks,

Ryan

Yup, all real, the Xianfeng cash is pretty impressive. Be sure to check the mintmarks on the reverse

Thanks Kenny, your expertise is appreciated!
