hi, i was just wondering, is there anything super important in your arm that would kill you if you got shot there? like upper arm near your shoulder but a little below

Well, there’s an artery near the armpit. In the shoulder it’s the Axillary, below the shoulder it becomes the Brachial. It’s the same artery, only the names were changed to confuse pre-med students. As I’ve said before, I’m not a doctor, but my advice would be, “don’t get shot there.”

I don’t know what bleed out times look like if that’s severed, but at a guess I’d say, “not long.” Probably under 120 seconds.
