Hiya @tdziemia, thanks for your efforts, completely forgot about diameters! They are 17mm, 20mm, and 22mm respectively.
Your first link doesn't appear to work, but the second is actually what I had believed to be coin #2 (owing to size and obverse script). Also, as a note, I believe that coin #3 is KM#616, or a Rumi Altin of Mahmud II, but the photos in Krause are so bad, and people online oftentimes get it so wrong, that I am very much open to suggestions.
I'm going hope against hope that someone can pull a rabbit from their hat for the countermark :/
