Questions about some pieces of Sumitomo

[Yellow Dragon]

Is this piece a version of Unknown Enemy? Note that this piece is like a slow version of this one, but it has a different title.

And what about this and this? It seems to complement each other.

Same themes, Sumitomo didn't take the Yamamoto route and decided to make a thematic continuity for his scores just like Kikuchi and Tokunaga did, so good ^^

More examples:

First Figure Majin Boo / The Terror Begins!
Goodbye / A Break in The Battle
Freeza's Army Invades / Freeza and his Horrific Power / The Ruthless Freeza
Beerus' Approaching Shadow - Beerus & Whis / Beerus' Approaching Shadow - Beerus' Prophetic Dream
Broly Evolves / Broly's Rage & Sorrow
