Question: Why does Norton lie and say that he "has company" and then make De Niro wait longer during the robbery? Sure, Norton double crosses him later, but wouldn't making his partner wait put both of them in danger of getting caught since it delays them and increases their chances of getting caught?

Answer: Norton already has an advance plan to prevent himself from getting caught. The delay is both to fluster DeNiro, and to prevent him from having enough time at the moment of the double-cross to come up with an alternate to handing over the prize without getting caught himself.
