i need help organizing this RCT2 Spritesheet

[White Polar]

Are these the raw files? If yes, then they already look fine to me. Just put all three of them on one sheet and submit it.

Edit: I guess RCT2 means RollerCoaster Tycoon 2.

Yes RollerCoaster Tycoon 2.

The issue i have is more of a "tidy them up" 

Also, there are 3 files 'cause the original file is too large, so idk where i can submit the full file.
