To my knowledge, there are no other post-sail pre-dreadnought ships still afloat.
Mikasa, Aurora and Huascar are afloat and in good shape. Mikasa and Aurora are slightly younger than Olympia. Huascar is closer to ironclad than predreadnaught. She has simple pole masts, but they were backups to the engine and were never used in combat.
