Actually it's Gungnir Spear, Samurai Shield, Samurai Armor, Samurai Helmet and Samurai Gauntlets.
At least in the version of the game I'm used to play (FF2 US). Maybe these items had other names in different versions of the game.
And the answer to your question is:
Battle Theme
Boss Battle
Dreadful Fight
Final Battle
Ring Of Bomb (when you fight against Rydia in Mist)
Cry In Sorrow (when you fight against Egde's parents)

Golbez Clad In The Dark (when you fight against Golbez)
Dancing Calbrena (when you fight against Calbrena)
