We present the identification spectra, obtained at the SOAR Telescope, as well as magnitudes and Gaia distances for 45 objects. Of these, 39 objects are identified as CVs, from which 8 targets show observational characteristics of mCVs, being 7 polars and 1 intermediate polar. The remaining 31 CVs in our sample are probably non-magnetic systems, in low (22 systems) or high (9 systems) accretion states. Six targets of the sample are not CVs (5 active galactic nuclei and 1 T-Tauri star). Among the 8 objects with mCV spectra, 6 are new classifications. Three polars were observed in low-accretion state, either revealing photospheric features of the secondary star and allowing the estimation of their spectral type, or presenting H{beta} Zeeman components associated to the white dwarf (WD) magnetic field. In addition to the results obtained in the first paper of the series, and depending on the confirmation of these classifications by observational follow-up, our results would increase the sample of known polars by about 9%.2020AJ....159..114Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cb : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2004)II/179 : Southern Spectrophotometric Standards.
