There were more than two inside the wartime Manhattan Project.
The two that were prosecuted were Klaus Fuchs (physicist, provided complete plans of the bombs including critical details of the MK-III) and David Greenglass (machinist, provided some "minor" information on machining certain parts).
One that was discovered and monitored carefully by the FBI was Ted Hall, but no action was ever taken. After the war he moved to Chicago and continued to give the Soviets information on improved atomic bomb designs and the hydrogen bomb. In 1962 in moved to Cambridge. He eventually retired from Cambridge in 1984.
Outside the Manhattan Project there were the Rosenbergs, who were executed. They were relatives of Greenglass and acted only as couriers.
There may have been others that were not even uncovered.
