Identification help for 5 coins [solved]

Can't determine presidency. These are British India coins (I think) and I have bought these for worth of silver metal, except coin #5 that's not silver.

1. 10.87 grams. Medal alignment


2. 11.14 grams Medal alignment


3. 11.21 grams Coin alignment


4. 11.1 grams Medal alignment


5. 9.22 grams Medal alignment. Metal is copper in my opinion.


6. 11.63 grams. I know this one, posting just to tell that I bought this one for worth of silver metal.  


 

1 & 4 both are of British India - Bengal Presidency. Probably https://en.numista.com/catalogue/pieces43505.html, but please verify the exact variety as these coins are with frozen date

2 is Shah Alam II Rupee (Shahjahanabad) KM#710 - Mughal Empire

3 is Muhammad Shah Rupee (Shahjahanabad) KM# 437.4 RUPEE (Type 437) - Mughal Empire - https://en.numista.com/catalogue/pieces50428.html
