Chris Hosey is a minor character that appeared in the first book. He sat in front of Greg Heffley in sixth grade. It's also rumored that Pete Hosey whom was the leader of the three teenagers that chased Greg on halloween was his brother. Greg was shocked when the teacher said they would be sitting there for the rest of the year.
In the movie, when the popularity list is shown, he is shown on the 20th position.
He could be Pete Hosey's brother, but still it stays unconfirmed. This, however, is unlikely considering that Pete Hosey is a movie character based off of an unnamed character in the books.
