Um... it's fine in the sense that they're all science and science-adjacent coursework.
I don't know I'd take all these in one semester. For starters, these are all extremely different disciplines that will stretch you mentally in way too many directions. It would be different if you were taking a bunch of hard courses clustered in one discipline, but you're learning like 6 different vocabularies here.
Do you really want to take analytical chemistry if organic was already a challenge? (I think I'd rather have hairpins in my eyeballs Oedipus style than study proton NMR again, or God forbid do math in chemistry like back in general chemistry again)... Same with E&M, which I can only assume is like a Physics 2+++.
For what it's worth, and the advisors will correct me if I'm wrong here, but if you retake a class you've already taken, I'm pretty sure they will either average both or omit one. So if you got an A in anatomy freshman year and you get another A this semester, it'll be a complete waste of time. If that is the case, I only see downsides to taking it.
Epidemiology and exercise physiology are fine if you have personal motivations to learn that content, but personally, if you know you're taking the MCAT soon, I'd be taking supplemental courses for that. Embryology, immunology, cancer biology, endocrinology, microbiology are all -ologies I would target. There's plenty of basic science to review that I think would benefit you for the explicit purpose of applying to medical school.
