  Historical observations of transients are crucial for studies of their
long-term evolution. This paper forms part of a series of papers in which we
develop methods for the analysis of ancient data of transient events and their
usability in modern science. Prior research on this subject by other authors
has focused on looking for historical supernovae and our earlier work focused
on cataclysmic binaries as classical novae. In this study we consider planetary
nebulae, symbiotic stars, supernova remnants and pulsars in the search fields
of our test sample. We present the possibilities for these object types to
flare up visually, give a global overview on their distribution and discuss the
objects in our search fields individually. To summarise our results, we provide
a table of the most likely identifications of the historical sightings in our
test sample and outline our method in order to apply it to further historical
records in future works. Highlights of our results include a re-interpretation
of two separate sightings as one supernova observation from May 667 to June 668
CE, the remnant of which could possibly be SNR G160.9+02.6. We also suggest the
recurrent nova U Sco as a candidate for the appearance observed between
Scorpius and Ophiuchus in 891, which could point towards a long-term
variability of eruption amplitudes. In addition, we find that the `shiny
bright' sighting in 1431 can be linked to the symbiotic binary KT Eri, which
erupted as a naked eye classical nova in 2009.
