I can't say I remember the exact specifics right now, but you can find everything you need in the walkthrough! ^^

I did take a look at the walkthrough and found the information for the green portion, nothing else though. The information needed for the puzzles is not marked on the map. Tried brute forcing the rest (trying every possible combination) but must've skipped the correct combination and don't exactly want to try going through it a second time.
I took a look!
So, the blue and red info for the 3 part 9 mushroom puzzle won't be available until later in the tunnels.
As for the answer key of the puzzle to the right of the blue mushroom, simply go straight up from the top of the blue mushroom (to room 4H on the walkthrough map)! You'll find a Mush smash minigame there, clearing it will reveal the answer ^^
