We don't know that The Episode where Cora first appears and "The Shepherd" are set at the same time - they cold be 10 years apart. Cora IS the Miller's daughter (this has been confirmed) so it means that she and Charming are around the same age.

We have no idea if Snow is the same age - she could be 10 - 15 years YOUNGER than Charming for all we know. It's never said if they are the same age.
