Cuanto cuesta means "how much does it cost" and the best choice would be "cuanto es" which means "how much is it"
1. Este
2. could be any of the three, but I’d go with esta
3. Esa
4. Aquella
These answers depend on how close or far the objects being described are from you, so I’m not sure if there’s any more context.
