Seven old Chinese coins [Resolvido]

Can someone help me identify these old Chinese coins, and wether they're real or fake? Thanks.

For starters, the "silver" coin in the top left is definitely fake. It has, for province name 'Kwangtung' on the reverse but 'Jiangsu' in Chinese on the obverse, so some forger somewhere probably didn't know much about numismatics.

The copper coin beneath it is this one; https://en.numista.com/catalogue/pieces15604.html
one of the types issued in 1906, but an exact variety cannot be established since the character in the centre of the obverse is not visible anymore. It looks real enough to me, though, since copper coins are faked less often; but as with all old Chinese coins be careful.

For the rest I have no expertise on those.

3) Northern Song Dynasty - Sheng Song Yuan Bao (cursive script)
4) Ming dynasty - Zhu Yuanzhang, as prince of Wu (1361-1368)
Da Zhong Tong Bao - Jing above - Nanking mint - DH#20.46 not yet referenced in Numista
5) Northern Song Dynasty - Emperor Zhe Zong (1098-1100) Yuan Fu Tong Bao - running script
6) Qing dynasty - Qianlong - This coin is likely genuine.

The Wang Mang spade coin (1000) looks fake to me : general aspect of the metal + the caracters on the left should not touch each other.

I don't know about the following ones, but you can have a look on this article : http://fakecash.blogspot.fr/2016/05/

Thank you all! :)
