Not really, they can grow to pretty large sizes, however, you could probably make 2 of them work if there arent really any other fish with them other than maybe various shrimp and bottom cleaners. But Discus require extremely high temperatures so finding compatible fish with them could be difficult.
So to answer your question, you could make them work but it cant be more than 2
