If you can't keep snails because of copper, then you probably won't be able to keep shrimp either. Too, ghost shrimp are not compatible with the red guppies.
Corys are schooling fish so perhaps you could get more than just one. Same for the neons. I would build up the schools of the fish you have before adding anything else to the tank.
