Help identifying some Chinese cash coins

Hi everyone

I've had these coins sitting around for ages, but I know absolutely nothing about them and I finally decided it would be nice to enter them into my Numista collection.

If anyone could tell me anything about them it would be appreciated.
I'm guessing the one on the top left is a modern souvenir/replica.

Apologies if any of the coins are upside down or around the wrong way!
Some of them might be a bit hard to read - can do a bigger photo if necessary

from top left to right:

4. Kangxi (Lin), FD# 2264

2. 3. 8 - Qianlong Boo-ji, FD# 2325

5. 6. 7 - Qianlong Boo-chiowan, FD# 2297

Thanks. Is it possible to identify the year or not?  Also, some of the coins you listed as the same are clearly different?  Forgive my ignorance about these coins!

1. no, they have no exact date on either side

2. the existence of different varieties

Thanks for your help!

first one is a fake

A coin with little dots on the background is mostly fake.
Indeed your first coin looks that way.
A correct date is indeed not possible, but if you google the emperor, you can find the period when they were made.
Shun-chi 1644-1661
Kang-shi 1661-1722
Yung-cheng 1723-1735
Chien-lung 1736-1795
Chia-ching 1796-1820
Tao-kwong 1820-1850
Shen-fung 1850-1861
Tung-chi 1862-1874
Kwong-shui 1875-1908
Shuen-tung 1909-1911

Chinese coins are read from top, bottom, left, right.
The other side is in mandarin (I think). Mandarin is read from bottom to top.
The two coins on the right should be rotated 180°
The curls should be left. The symbol on the right is the mintplace.
1, 5, 6 and 7 are Boo-chiowan (Peking), Hu-Pu Board of Revenu
2, 3, 8 are indeed Boo-Jiyen, Chih Mint, Paoting, CHIHLI
Corrections welcome
