Take your time.
No. There is no need for five times two. It's just five direction for a 4D space. They balance so that (1,1,1,1,1) = 0. This is the simplex geometry. The components do not require any sign and instead the construction is the generalization of sign, just as the one dimensional form is (1,1) = 0 which is to say that  1 + 1 = 0 . Five signed numbers do have inverses but each individual sign does not carry a direct inverse as they do in the twosigned numbers.
