Heya mate, thank you!
I am not sure I follow. You mean the locations/number of frames for the standalone sheets or for those labelled as RMK?
If you mean the ones labelled as RMK, they all follow the standard placement and frame count of RPG Maker default sheets for Side View battlers: https://rpgmakerofficial.com/product/MV_Help/page/01_11_02.html
Just the size differs for bigger characters, such as the Slime Queen.
