The slender flowers with the two separate marks look like Gal. gracilis. If the leaves are applanate (flat, not wrapped around each other at the base and not folded back at the edges) as I suspect they are then it's gracilis. If the leaves are rolled around each other at the base then it's elwesii, but I think you'll find it's gracilis.
The other plant I'm not so sure about. It looks like Gal. plicatus but the leaves aten't very typical for plicatus. If the leaves are folded back at the edges, then it's plicatus. If they're flat on some edges but folded back on others, then it could be a hybrid. Can't say more than that. Were they from seed?
