1. A weird question in my opinion but I may have interpreted the question in the wrong way. I'm assuming that if you have anything with n = 2 you must have something in n = 1 also.
You can have 2 electrons in n = 1 but only one of them can have ms = -1/2.
You can have 8 electrons in n = 2 but only half of those can have ms = -1/2
