Ottoman Coins, [resuelto]

Hello, I recently acquired these from bulk poundage and need help with identification. I don't know much abou these so any help is most appreciated.

Hello. The most important thing with Ottoman coins is the numbering/date system. You can acquaint yourself here. https://en.numista.com/numisdoc/calendar-islamic-30.html

So for the first coin I see a date of 1255 (١٢٥٥) and a denomination of 20 (٢٠), with a regnal year of 21 (٢١) .  A search gives this.  

For the second coin I see a year of 1277 (١٢٧٧) and a denomination of 20 (٢٠), with a regnal year of 1 (١).  A Search gives this.

The last two coins are actually Egyptian, not Ottoman, but the same numbering/date system applies to them as well.

Thank you, I was able to id the other 2 as well N#140849 N#10923
