4 unidentified Arabic coins

Hello everyone,
Here's one last batch of mystery (Ottoman?) coins I'd like to identify. The smallest (an Ottoman para was my guess) is 12 mm wide, while the other three are between 17-20 mm. Please let me know what you think. Thanks!

on the 3 'brown coins, I can read MISR (Egypt)
Top coin:
AH1223, Regnal Year 29? (1837AD)

Right coin RY 29, date is worn off
propably 1 para

bottom coin RY 1 date is not readable

Thanks for the help again, Petrus! I believe that this is the top coin: https://en.numista.com/catalogue/pieces33926.html

I'll do some digging as per your suggestions for the other ones. I appreciate the help :)
