Hello I would like to ask opinions about this theropod tooth fossil. The seller says that this tooth is from Aguja Formation and this tooth could be Teratophoneus's tooth. I am not sure whether this is true so if anyone has opinion about this tooth, I would be glad to hear it!

Teratophoneus is only known from the Kaiparowits formation in Utah.  There are no described tyrannosaurids from the Aguja Formation.  It should be identified as Tyrannosauridae indet.

Agree on Teratophoneus not described from the Aguja, did the seller provide you a locality where it was found?  What size is the tooth?

The last photo looks like a premaxillary tooth but I cannot determine what it is from the other photos.  Any serrations present?  Preservation is awful.  Like to see a photo of the base and better infocus images of the first two..
