The two blue things are pointing directly at the bright light below the menorah. It's an optical artifact, something like a lens flare you get from the sun.
These are clearly angels. Or Photoshopped. Or UFOs. Or Photoshopped angels made to look like UFOs. I also wouldn't entirely rule out some kind of reflection. But I know I've never taken a picture of a menorah and had blue photoshopped UFO angels in it.
