Without changing lower receivers, what calibers can fit in the AR-15 lower? I know .22LR and 9mm fit in it, but what else can it be converted to?

Wow, that's awesome. Thank you for listing all of these. Sounds like the AR-15 lower is a highly adaptable "gun".
7.62 will not fit in a normal AR lower. I don't know why people keep saying it.
Are there AR-styled rifles that do shoot 7.62? Yes. But do they use the same lower as a normal 5.56 AR? No.
This is why I mentioned it, but don't know if the magwell is somehow different, it doesn't look like it.
