NGC 1502 and Stock 23 are real. They're star clusters. The other names aren't familiar to me, but they might be real, too.
You might consider placing events in one of those clusters.
The resource most often used to get real information about real objects is the Simbad astronomical database. One of its search pages is at http://simbad.u-strasbg.fr/simbad/sim-fbasic
Just type in one of the official names of an object and Simbad will display lots of info about it.
Unfortunately, although there are BF catalogs, 528 and 529 aren't recognized by Simbad. Maybe Steve can comment on that.
Information about many star clusters is also available from WebDA. Its search page is at https://www.univie.ac.at/webda/navigation.html
According to it, 5 stars that are in the Hipparcos catalog (used by Celestia) are in the vicinity of Stock 24. The cluster might consist of 30 or so stars.
Precise 3D positions for ~1.3 billion stars are expected to become available later this month when Gaia's second data release is published. That should make it possible to provide more accurate numbers.
ETA: and will likely require some significant ret-conning of some of OA's articles.
