Is this biologic width invasion?

Do these crowns need to be redone? Is there cement on mesial of #9 that is a concern? Or not a big deal? Is there BW invasion here?

From the Xray there doesn't appear to be BW invasion.
Those crowns have very little natural core structure, and I'd advise you not to bite much with them; keep them for appearances only. You might be able to improve the forces exerted on them by re-prepping deeper and changing to PFMs. If they're looking a bit unsightly, that might be a way to consider, but consult with a prosthodontist. Even if all you do is a consultation, it'd be worth the $.
