the ones that have two lines ( the small black line on top of the long line that runs the length of its body) are deffinately biffas. the others could be zonatus or fenestratas? hard to say forsure

The lower 2 pics of the bifas appear to be males, because of the fin extensions, the top 2 pics look female, rounded fins.
The top 2 zonatun(?) pics could be youngish zonatum. If they are, they will get a green sheen in the upper part of the body when they get older.
