4 unknown coins from Indian states

Hi everybody,

I have here 4 coins from Indian states, I think. After searching in numista I found it what a little likes. I hope it is correct? Is there an expert who can help me to find the right identification of these coins, the script is for me incomprehensible. How can I find the right date or year on these coins? Is the KM# ok?

The first coin is, I think from Moguhal Empire KM#50.1, value is 1 rupee, material and dimensions are equal with numista data.



The second coin is, I think from Hindu Kashmir? I can't find a coin like this in numista. who can help to identify this coin, The diameter is 18 till 19 mm, thickness 3.3 mm, weight 5.82 gr, material Cu. has this coin a market value?



The third coin is, I think the Empire of Sikh. KM#20.1. The problem is that this KM-number likes but it is not totayl the same. Is the year 1881?? The dimensions are 24 mm, 3.2 mm, 11.11 gr, mat. silber.



The fourth coin is, I think also from the Empire of Sikh. KM#21.1. The problem is that this KM-number likes but it is not totaly the same. Is the year 1884?? The dimensions are 24 mm, 3.2 mm, 11.13 gr, mat. silber.
