Happy, Willy's other son, is similar to Willy lost because he has never allowed himself to turn his face toward defeat. Happy did not have the athletic background and was focused on women, but he was a promising individual who was smart and had a well built frame. Unlike Biff, Happy is a regular guy and has a job, hopes for promotion, and is committed to conform to societies rules; he also never acquires his ultimate self-knowledge and realization of the truth. Unfortunately, he remains the Loman that he always was, incapable of interpreting the message of Willy's failure. Happy also needs to pretend to be more than he really is (like father like son). .
Charley, the good friend of Willy, is successful through financial means but Willy feels that he lacks the personal presentation and style of true success. In the opposite sense, Charley helps break down Willy's belief that to be well liked is the most important quality in a salesman. Willy cannot understand Charley's success, his own formula seems to have broken down, and yet he can never admit this. Charley's success confuses Willy because he wants to make his children well liked, but he knows that Charley has succeeded without it. .
There is also Ben, Willy's foil. Ben has lucked onto amazing success on another continent and wishes for Willy's success, just as Willy does. He is an example of the very small population who are successful without much work. Every time that Willy thinks of the American Dream, he thinks of the achievements of Ben's lifetime. Ben is a ruthless businessman, who is rich and adventurous and not confined by any psychological restraints. Other than by monetary means, Ben does not see why Willy and his sons cannot be just like him. Willy knows of Ben's success techniques, but he is not motivated enough to tell his children to go to another continent to get that success.
Bernard is Biff's foil, having been a smart individual who works hard at achieving success.
