For the previous pictures, it is difficult to make a guess with a few words since I have not seen a similar one till now.
For the new ones:
The first one is
Bıçak elde gerek dilde sübhan
Ya Muhammed kıl şefa'at ümmetindir
One should have knife(yataghan) in his hands and the Subhan (popular name for Sorat Al-Isra from Quran) in his tongue.
O Muhammed! Intercede on the day of Judgement on the behalf of
Hüseyin Ağa,
who is one of the believers
Funny thing is the person, who were writing this, should have been out of space at the end and had to omit last letter of
süphan and the name of the owner (which usually comes after
ümmetindir) from the inscription.
The writing on the second cartouche is also erased but from the words that still stand intact I was able to make a guess:
Sinn-i adaya ya Rabb bu bıçağı kıl nişan
Sahibini daima muzaffer eyle olsun alişan
May God make this knife a sign on the bossom of enemy
May God make the owner of this knife always glorious and illustrious
The third one is hopeless for the moment.
