Does jonas die in the book The Giver?

Jonas lived. It is not perfectly clear as to what he saw at the end of the giver, but in the third book it mentions a "a leader who came to town on a red sled" and mentions Gabe, his little brother. Also in the new book, The Son, by Lois Lowry, it is the story of the real mother of Gabe, and it talks about what happened to him after he came back with Jonas.
