They are beautiful. Note: 'Hermosas' refers to something feminine because it ends in an 'as'.
It means: "How do you say that they are beautiful sisters?"
Did you mean 'Ay! que hermosas!', if so: 'Oh! what beautiful girls/women!' Or, because Spanish words are all masculine or feminine, and 'hermosas' is feminine plural, it could mean some objects, for which the nouns are feminine in Spanish, are beautiful, e.g. 'Ay! que hermosas (manzanas)!' = 'Oh! what beautiful (apples)!'
