Will the SIM card from my iPhone 8 fit my iPhone 12 Max Pro?

1. Yes.

2. Yes, unless the iPhone 15 was originally sold in the USA, in which case it doesn't have a physical SIM card slot.

If an iPhone is locked to a carrier, the SIM card will need to be for that one to work.

Yes, it will fit and it should work. However, it's possible you won't be able to use 5G. You may need a new SIM for that.

Whether or not you can move the SIM card from your iPhone 12 Pro Max to your iPhone 15 Pro Max will depend on where you bought the iPhon 15 Pro Max. If you bought it in the U.S., it doesn't have any physical SIM slots. You'll need to get a eSIM from your carrier. If you bought it outside the U.S., yes, you can use the old SIM.
