From those pictures, that rainbow appears to be a female Melanotaenia boesemani. If you got a close up picture I could tell you for sure, I'm a rainbow guy
The rainbowfish appears to be a female Turquoise Rainbowfish
No, from picture 6 the rainbow shows the tell tale vertical bands that all boesemani have. You can't always go by color, there are other signs like fin shape and body shape. It's a little difficult to tell without a closer picture.
