Thanks for your detailed reply. He's not my cat unfortunately. I was taking care of him for a short while and would love to get one of my own!Very lovely! Is it your cat?
I would describe this cat as a brown classic tabby and white domestic shorthair. Classic tabby refers to the cat's tabby pattern. This is one of the oldest mutations in the domestic cat, and is characterized by bold swirling tabby markings, usually including a rounded "bullseye" on the side of the cat, which can be seen in the first photo in your post.
In these pictures, I'm not seeing obvious evidence of ancestry from the Bengal breed, or any other specific breed. Although it's certainly possible that this cat may have some breed in its ancestry, most cats are not any particular breed, and are not "mixes" of breeds, unlike dogs.
