They're all specialized DBs. There is no general case.

You don't need any terms, they're all just databases.
Relational is specialized too - in dealing with relational data, foreign keys, normalization, joins, etc.
ACID is just a feature of a product, not tied to relational as there are relational databases that don't offer it or can have it disabled. Tradeoffs and understanding your data apply to every single type of database.
Perhaps it should be said that relational is DB that's for general purpose, while specialized (key/value, graph, etc) requires you to understand your data so you can make proper trade-offs when picking specialized db. You are not getting those features advertised by other databases for free.
