Other than really bad quality photos?
Ummm possibly a spadetail in the 1st pic? The last one is possibly a female pk and there might be a female spadetail too?
To be honest i think anyone's gonna struggle to identify them from those pics
young vts (and i assume those are young fish still) will look like spades until their tails "fill in" more. from those poor quality photos, id assume all are vts. young(ish) ones at that.
cheers
