Noah and his five friends: Abner, Benny, Chaim, Diego, and Ezra, were hanging out when Noah spotted a wallet on the floor. Noah has a poor memory, but he remembered that it belonged to one of his friends.
Therefore, he decided to question his friends about it. Their responses are furnished hereunder as follows:

• Noah: Whose wallet is this?
• Abner: That's mine.
• Diego: You're lying, Abner.
• Chaim: That's right, Abner, you are lying.
• Benny: Abner is not lying, guys.
• Diego: That wallet belongs to Chaim.
• Ezra: That's right, Diego is telling the truth.
• Benny: No, Ezra. That's your wallet.

Noah remembers that at least 2 of his friends are Knights, who always tell the truth, while at least 2 are Liars, who always speak falsely.
Unfortunately, Noah cannot remember which of his 5 friends are Knights and which are Liars.

Determine the types of the five friends. Who owns the wallet?

The question is considered missing data. It is difficult to determine whose wallet is, the situation is quite general. Need more data to getting over it
