3 polypterus ornatipinnis
4 some kind of goby (they r brakish )
5 Geophagus
6 JD
About JD's they have a distinct mouth at least to me and can always tell them by the shape of the mouth. Also don't forget u have blue, electric blue and regular JD's. the one in the store seems juvie and a little faded in colour cuz of stress but that will color up once settled in ur tank.
In a 55 g u can do any fish up to 8-10" range IMO. Also remember that maximum sizes are the maximum sizes these species attain, u can probably count on an inch or 2 less then that.
from the pix u posted u can get the JD or the Geo. If u like bichirs u can get the senegal bichir for a 55.
