I agree that these tags are not needed.
For the former I suggest to retag the two questions (the tag then goes automatically away after a day).
For the latter we might wait for a few days if the question "survives" or not. If the questions should be deleted the tag would be gone too.
For tags that only have a few questions to them, retagging is usually the best way to get rid of the tag. However, except in very clear cases, it makes sense to raise the subject on meta, either via a dedicated thread or in the tag management thread mentioned by Martin. The current version is Tag management 2019 (usually a new one is posted each year).
I don't think it applies in this case, but if you have a proposal for more general tag that could be used instead then moderator could "merge" the over-specific tag into this more general tag.
By contrast, directly deleting a tag (sometimes playfully called 'burninate') is something that even moderators cannot do, we need SE staff for that. It can be done if it is needed for a large tag, but for non-sizeable tags it is better to deal with it by retags and merges.
