No… Apple stopped signing it.

No, not any more.

iOS 8 is no longer being signed, so you can't get it. You have to update to 9.3.1; there's no way.

I don't see why not, though you may not be able to use that version depending on which iPhone you have & also may not be able to download it straight to the iPhone.
