I don't think any of those import is bad, at least not on the criteria of duplicated way/relation tags. In the low count cases, the duplication is likely to have happened during later edits rather than the initial import. Today duplicating tag on way+rel is considered bad practice, but that came about slowly (standard practice used to be to tag the way only).

Duplication is also fairly harmless (as long as the tags don't contradict), and some would argue that it isn't worth the version churn.

Broken polygons on the other hand (which were probably broken manually, not by the imports) are worth fixing. They are easy to detect but not always easy to fix. Some error types might be mechanically fixable, but I guess that most need human intervention.
