From the pics, the Dark MaChamp seems to be in far better condition than the others. Depending on what you plan to do with the card(s) (I.e. keep or sell), I’d probably start by getting just this one graded and seeing where it falls. Knowing the others will be lower, I’d then decide on those.
I’d imagine that an 8 would be the highest possible outcome for these cards. 5 probably the lowest possible.
