The Vale of Questioners

You arrive in the Vale and begin mingling with the locals, trying to bring up the topic of The Sorceror without insulting anyone. The responses are, to say the least, curious:

A Valeman named Arthur asks you: “Am I the Sorcerer?”

A Valeman named Bernard asks you: “Am I the type of triber who could ask whether I am not the Sorcerer?”

A Valeman named Charles asks you: “Am I the type of triber who could ask whether the Sorcerer is the type who could ask whether I am the Sorcerer?”

A Valeman named Daniel asks you: “Is the Sorcerer a No triber?”

A Valeman named Edwin asks you: “Are the Sorcerer and I of the same tribe?”
