1 - KP
2 - Solf
3 - Maria
4 - Silver?
5 - Dexter?
6 - ????
We still have one knife unaccounted for, discarding the theory that some Unknown Trap X was used to make Ryoko appear as if she had been stabbed by a knife for the express purpose of fooling me. KP can't kill and his knife was more like a sword. Solf I can't say anything for (if he has it with him now he can show you the knife, and if it has no Ryoko blood on it then he could be cleared theoretically). I sprayed my knife with Luminol, on camera. Silver cannot be the culprit. Dexter is already dead so unfortunately we can't get anything out of him.
I think whoever has the last knife, if they have it on them right now, needs to show it to everyone else in the trial room to prove there's no blood on it (Solf needs to do the same to clear himself as well). To do otherwise is as good as confirming that you either disposed of or hid the knife somewhere after using it to kill Ryoko.
