Regina and Cora are lesser witches? They could/can both hold their own very well in a fight. And the magic in the Mills family was genetic. Regina and Zelena had it because Cora did.

As for Elsa and Ingrid, ingrid probably always had it inside her, and she just released it at an older age. well not really but compared to Elsa... Elsa's powers were the price of Gerda taking the memories of everyone in Arendelle. But she was still born with them.
