I can’t see the first one, it’s not letting me.
Second one looks like peacock to me, not sure what you’re seeing there.
Third is also a real peacock, but that’s what happens when you photograph them in just the right kind of lighting. It’s a camera effect, it’s still normal peacock.
Four one has been posted four times already today! It’s a green emperor, not a peacock male, but the green emperors have peacock accents on them, so it can be easy to get them confused, if you don’t know the colors really well.
