Most of them do indeed reappear in Nademonogatari.
Reviewing the official anime translation for OFF & MONSTER season (no LNs referenced), it should actually be:
Divine and maybe Wrath/Flirty are indeed used in older official LN translations, I think, yeah. Thanks to whoever made the Wrath one as I didn't get around to that.
As for the topic at hand, I'd be somewhat fine with only having a separate tag for Divine Nadeko (god) so long as the others are consistently tagged properly. If they aren't, then it's much easier and more likely for people to tag a distinct costume. We need to make more wikis to identity them beyond the pics in the Sengoku Nadeko wiki though, else people won't know which character tag to use.
It's also very annoying to search for shikigami Nadeko forms because, e.g., there are fawning nadeko posts where her bangs aren't pinned up in a hairband (post #1613831, post #4677495, post #1082474, post #1107121, post #1076337), or posts where he her bangs are up but she's not wearing a camisole (post #8145201, post #8350399, post #8493981, post #1613831), but I'm looking to search for more than just that particular general tag + Nadeko.
I think most of the forms are clearly identifiable enough to warrant their own tag. As different personalities and copyrights, they're practically different characters. Including the mangaka outfit and sundress clones. If I had to guess, I created Sengoku Nadeko (Sundress) instead of "caramel ribbon cursetard" because that OP prominently features both the non-canon sundress clones and the mangaka look that also appears in Nademonogatari proper, so I'm resistant to nuking it. And it's easier to search this way. I think the only two missing a tag are the Ren'ai Circulation and Mousou Express ones, but I'd still rather those have a character tag created in the future instead of the status quo. Present Nadeko, on the other hand, is one tag for two appearance because the only difference is clothing (casual vs. tracksuit; see wiki) and not hairstyle, personality, or copyright.
There's an argument to be made that the mangaka one is also Current Nadeko because the hair length is the same and it still looks like she cut it herself, but the cap hides it and it's quite a different outfit (or again, two outfits; Current has like four). And Buruma Nadeko kinda is officially a subtype of Meek Nadeko; same hair and personality after all. Can maybe resolve those another time.
