For Neptune, a possible name could be Nerida? Nerida turns up two meanings when I search for it; in Greek it means Sea Nymph, daughter of Nereus. And in Indigenous Australian it means Water Lily. Fit's the water theme and has the appropriate letter? Plus, Neptune was the Roman equivalent of the Greek God Poseidon, so the Greek meaning ties into it as well.
