what antibiotic would be most effective for pneumonia-- amoxicillin, ampicillin, or penicillin?

All the same: These are all essentially the same. They would be effective for some types of pneumonia, but would not be the first choice if you were treating pneumonia without knowing culture results.

Depends: Pneumonia is an infection of the tissues of the lungs, and can be caused by many different organisms, including viruses, bacteria, atypical organisms, fungi, and even parasites, among others. The antibiotic of choice will depend on the bug and its sensitivity to antibiotics (if at all).

None : None of these would be very effective for many forms of pneumonia. Usual treatments are a quinolone antibiotic such as Levaquin (levofloxacin) or a cephalosporin like Ceftriaxone plus Azithromycin or doxycycline.

That should work: Group a strep is susceptible to most antibiotics such as amoxicillin. See your physician for a prescription.
