                         magnetic cataclysmic variables (mCVs) among candidates selected 
                         mostly from the Catalina Real-Time Transient Survey. 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 Hi3 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%.",
