Asian coin to identify [solved]

I am not an expert on this so I need your help.

1. I think is this one. https://en.numista.com/catalogue/pieces162214.html

Is it possible to identify the variant?

2. Probably this https://en.numista.com/catalogue/pieces1133.html
But I have no idea which variant.

3. https://en.numista.com/catalogue/pieces19755.html
Same help need it with variants.

4. https://en.numista.com/catalogue/pieces31485.html
I am quite sure this one is the first variant with plain reverse.

5. And the last one https://en.numista.com/catalogue/pieces40837.html
I think I got this ne right but just to be sure..


Thank you in advance for your help!

Hi,

The pages are correct.
The varient of the coin #2 is DH#22.203.
For coin #3 I'm not pretty sure but looks like DH#22.252 or DH#22.253 for me.
