Your last shot reminds me of pics of the old mother in law, but hers was taken from the other end.
The meter will give you correct readings for what it's pointed at, roughly the center 1/3 of the viewfinder. I assume that you set the camera's ISO correctly. Do you have a manual for it? The A-1 has multiple ways to set the exposure, so reading it is a good idea. Just google "Butkus Canon A1 manual" and he has them. $3 donation, and they're well worth it. He's a treasure on the internet for manuals.
Without another meter to compare it to, it's hard to know if your camera exposes correctly in low light. In any case, inside shots w/ a FD 50 1.8 and 400 film will often give you meter readings of 1/30, 1/15, or less. Ck the manual. You will learn quite a bit. Those are great cameras.
