they're adaptions of visual novels so while the game order is Hearts, Clover, Joker, and so on (Omochabako and Diamond which don't have manga adaptions) the manga adaptions are actually done independently and some have multiple adaptions following different routes from the visual novels. basically it's totally possible to pick up any of the manga adaptions and start there, altho it's probably at least a little recommended to start with the first Alice in the Country of Hearts manga for a reference point given that there's no good translation of the game (the official English version of it is a terrible mechanical translation that ranges from awkward to nonsensical).
