ID of corys

[Palemon]

I just received 12 Corys, bought as Corydoras Napoensis. They feel pretty off to me but given that they're really young I'm not sure.
Some feel a bit like Elegans (such as the one on the right).

They're in a quarantine tank with Gh6, PH7 at 25.5°C for the time being.

I think that left hand 3 are Elegans and the other 1 on the right is napoensis. Elegans tend to have vertical strips.
