First shot at a tracklist, most of this is all katakana and simple words so it shouldn't be too difficult. Also, a significant number of the track titles are the same across the entire series. Notes below:

03 Prologue
04 Your Army BGM 1
05 Your Army BGM 2
06 Your Army BGM 3
07 Enemy Army BGM 1
08 Enemy Army BGM 2
09 Enemy Army BGM 3
10 Scenario Ending
11 Game Over

16 Unused Music 3

28 Scenario Ending
29 Game Over
30 Epilogue [Royal Guard]
31 Don't stop your dream
32 Unused Music

M04~06,19~23 I used "Your Army" since it means "One's own army or forces".
M19 I think "ナイト" is almost certainly "Knight" not "Night' given the setting of the series.

28 Ending 4
29 Requiem

M04~M10 specifically used "Ally" (it's different from "Your Own" in Disc 1), I presume these are the tracks that play for you and your allies (as opposed to the "Enemy ..." tracks)
M15 邪悪なるもの could probably be "Someone Becoming Evil" or something like that but I looked up the track on one of the original albums (TYCY-5403) and it's "Die boese Person" in German, which means "Evil Person" so I just went with that.
M19 Left the umlaut in Boeser

There is a note in Disc 2 about Ending 3 (also on the Sweep Records webpage) "※「エンディング３」は「エンディング２」の終わりに含まれており、実際のゲームプレイで聴けるものと近 い状態になっています。". Basically says "Ending 3 is included at the end of Ending 2 because that's the state it is heard in actual gameplay."

Pretty much a copy and paste from Disc 2 with the addition of 2 Allied Reinforcement songs (M12~13), an Enemy Reinforcement song (M24), and then a handful of different tracks after M24.

Nothing notable here except the M4/5 swap per the printing error and again a few different tracks towards the end.

Disc 5

01 Supplement 1
02 Supplement 2
03 Supplement 3
04 Supplement 4
05 Supplement 5

M01~06 Supplement sounds better in English (compared to Additional) when there's no noun to describe what "Additional" is referring to. It's understood that it's music but just the word "Additional" alone sounds strange.

- I'm not sure if this game was ever localized so some of the character and location names are taken from Langrisser.info
- I tried to make a distinction between character themes (...'s Theme) and location/organization themes (Theme of ...) but I don't know if this really matters.
- M34 is closer to something like "Until Motion" but I think it's probably a song or something that plays before you mobilize your units so that's the best I could come up with.
- M35 must be different variations of songs in encounters when you have different advantages or something
