The United States began experiments at the lunar base. How many people can live there?

After Apollo landed on the moon, the United States wanted to establish the first lunar base. Imagine sending a cargo hold with landing support and a lander with radar to the moon. This lander can also be used for manned flights, and each lander flight can carry six astronauts. As long as there is a cargo hold and a lander, a base can be established on the moon. No more than 12 people lived in the moon base and lived in prefabricated shelter for 3 ~ 6 months.
