No, this is not normal - I would definitely recommend taking Magic back to the vet. Pus coming from the vagina in an unspayed female cat is a common sign of a serious uterine infection called a pyometra. This is a life-threatening problem that normally requires surgery to remove the infected uterus. Antibiotics can help for a while, but they are rarely successful at eliminating the infection - this is why surgery is the preferred treatment for this problem.

    No, that is not normal. She may need a longer course of antibiotics or possibly a different antibiotic. A culture of the vaginal discharge is warranted so that your vet knows exactly what bacteria are present and then what antibiotic is the best option at eliminating the bacteria.
