We report additional BVR-band photometry for the novae candidates - Nova M31 2013-11a (ATel # 5539, ATel # 5569), Nova M31 2013-11b = red LPV (ATel # 5569, ATel # 5640), Nova M31 2013-11d (ATel # 5605), Nova M31 2013-12a = Swift J004249.9+411457 (ATel # 5569, ATel # 5677), Nova M31 2013-12b = PNV J00425172+4118142 (ATel # 5671, ATel # 5723) and Nova M31 2014-01a = PNV J00431362+4114469. The observations are carried out on three nights at two different observatories:

50/70 cm Schmidt telescope + CCD FLI 16803, NAO Rozhen
35 cm Newton telescope + CCD SBIG 11000M, SAO Plana (ATel # 5558)
