G=-nFE

Why is the "n" in this equation always positive even when there is a negative change in moles?

n is simply referring to the number of moles of electrons transferred. If it were delta n, then a negative change in moles would result in a negative value for delta n.

The only factor that changes the sign is E, so that's why knowing E can tell you whether it is spontaneous or not. n is simply the number of moles like in previous equations.

n just means to write the number of moles!
