Please help me ID these three

I can't figure out what these three coins are. The first one I suspect is from an Indian princely state. The second I was guessing maybe Iran? The third I know I've seen before but I feel like I looked at every Middle Eastern and North African country and I can't find it.

Second is Iran 25 dinar (can't make out date), third is Sudan 5 milliemes (1971).
First one I'd have to look up, not that familiar with Indian coins.

 

Thanks! I think the date is too worn on the Iranian coin. I hadn't thought of Sudan. I bought some other Sudanese coins from the same bin but they were the older style that I'm familiar with.

 

Your first coin looks like a Indian States, Bengal Presidency,1 Pice, 1830, KM-57,

 

Thanks!
