The answer to 5c) is twice the value in a. Why don't the electric potentials from both protons cancel?

Potential is a scalar measurement. So has no sense of direction. If the potential due to one positron is x, then the potential due to 2 positrons (no matter where theyre placed around a point) is always 2x.
Ahh okay, thank you! On a side note: why is this? Why is electric potential scalar, whereas electric field strength is a vector?
