Yep: Nominative, Vocative, Accusative, Genitive, Dative and Ablative.

Ancient Greek doesn't have Ablative -- instead it merges the senses of dative and ablative.

Don't ask me to remember what they're used for, though. It's been a while.

Croatian splits ablative further into locative and instrumental (BTW, you got your order wrong: is it Nominative, Genitive, Dative, Accusative, Vocative, Ablative - how else could you recite examples of declinations by heart ). I can remind you of usage if you want, but I would have difficult times doing that in English
