For the Nb#4 we get in another era the North Song Dynasty whith the emperor Hui-Zong, 8th emp. (1100-1126) who was painter and an art promoter.
4th era of Huizong (1111-1118),
Zheng-He Tong-Bao - Li Script - DH# 16.441
The authenticity of Chinese coins older than a millennium is hardly decreed just by looking to a scan. In any case, I can not.
The Nb#5 is from another dynasty : the Ten Kingdoms (907-960)
Former Shu Kingdom (907-925)
Wang Jian (907-918)
Yong Ping Yuan Bao c/wise - DH# 15.30
You might add this coin that is not yet referenced on Numista Under:
China - Empire - The Five Dynasties and Ten Kingdoms (907-960)
The #6 is not from China but from Annam, Nguyễn dynasty, Nguyễn Phúc Vĩnh San, the puppet emperor of the French who enthroned him at the age of 7
Duy Tan Thong Bao (1907-1916)
With the #7, get back to the founder and first emperor of the Song dynasty in China : Emperor Taizu of Song ( 927–976) who reigned from 960 until his death in 976.
Song Yuan Tong Bao, small characters with dot on reverse : DH# 16.1d-g
The #8 is from emperor Shenzong of Song (°1048 +1085), who the sixth emperor of the Song dynasty and reigned from 1067 until his death on 1085. Second era "Yuanfeng" (1078–1085).
But in fact Japan was not miniting coins from 960 up to the 17th century, chinese coins were extensively used as currency, so this coin is actually a Japanese copy of the Northern Song:
Yuan Feng tong bao c/wise, large Tong, Li script
DH# 16.234.
We can recognize the square head of Feng, not with three strokes.
1 Mon Yuanfeng; regular script; Nagasaki Trade Coinage
The reference is
DH# 25.62, this coin is relatively common.
#9 and #10 look very strange

perhaps temple coi ns or charms ?
The #11 is from the Qing dynasty
Tongzhi, but the reverse should not be plain wihout the mint
#12 is from the Qing dynasty, emperor Xuan Zong (1821-1850)
Dao Guang tong bao - mint Aksu, Xinjiang, Square head tong
DH#22.652 struck between 1821-1828
This coin is not yet in the Numista database.
And, to finish with the #13, back to Yuanfeng, 2nd era of Shenzong (1078-1085), the 6th emperor of the Song Dynasty from 1067 to 1085, that we already met for the #8.
Now it's written in
Running script
So lets other collegues clarify these remaining coins 
coins #9


coin #10


Why a plain reverse for coin #11 ?


and I've got a trouble with the reverse of coin #6
