Hey,
Discus are still not going to be a good choice. Your friends tank must have a proven spawning pair of Discus. Angels and Discus will not mix well in a small tank, and neither will Discus and Rams. If you want Discus it will need to be a species only tank, with maybe a shoal of bigger tetras that won't get eaten (Red Eye for example.) You could also sneak in a shoal of Corydora if you wanted, but they would have to be sterbai. Again, as mentioned, most Pleco with try to get a taste of the slime coat on the Discus, and personally I wouldn't put a Pleco anywhere near my Discus. Don't know if the dimensions where already listed, but what are they? If you want Discus, this would be a good stock:
5 Discus
6 Red Eye/Black Skirt etc.
4 Corydora sterbai
The only thing I could suggest to you, if you want Discus, Angelfish, Ram, Dwarf Gourami etc. etc. is to get a bigger tank.
