Pretty sure most are the main composers. At the very least they each had their role, although track 10 from the first disc and 07 from the second --Castlevania and ESPER DREAM--were done by James Banana / Kinuyo Yamashita.

24 Couldn't find concrete evidence, but everything seems to point Goro Kin (Kingoro) as the composer. NOTE:
One of the scans for
F-1 Spirit + F-1 Spirit ~ 3D Special has a composer listing, so maybe someone could translate to make cross reference.
25 Again, no concrete evidence, but everything seems to point Yuji Takenouchi as the composer.
26 While this game lacks staff/credits, upon finishing the game a small blue window appears saying THANK YOU! accompanied by four names: HOSHINO, (Let's roll!) KATO, MINACAWA, and IWAO (

27 This one's rather strange... The staff for this game resembles that of a movie, and while people are credited for the game, Tonma-kun's Papa doesn't seem to be mentioned: Steve Kaufman, Frank Bundra, Frank Pellegrini, and Marv Hermanson. (

30 Is Uetaka another pseudonym of Harumi Ueko? Because that's all I got, again, from MobyGames, so take it with a grain of salt.
Phew! Damn that was exhausting! I'm out for the day...
