We report the following spectroscopic classfications for the transients detected by the Tsinghua-NAOC Transient Survey (PSN J03581436+3541327, PSN J08294049+4346533, PSN J09351328+5028219, PSN J12393982+1124426 and PSN J08572629+4845195; see also the IAU Transient Objects Confirmation Page). All spectra were obtained on UT 2015 Jan.21.6 - Jan.21.8 with the 2.4-m telescope (+YFOSC) at Lijiang Gaomeigu Station of Yunnan Observatories. Based on the spectral comparison tools SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al. 2008, A&A, 488, 383), the classifications were given as: (1) The spectrum of PSN J03581436+3541327 matches with the normal type Ia supernova SN 2003kf at t = +19 days relative to the maximum light. Given a redshift of 0.057 (from the SNID fit) for its host galaxy, an expansion velocity of about 11700 km/s can be deduced from the Si II 635.5 absorption minimum; (2) The spectrum of PSN J08294049+4346533 is similar to that of the type Ia supernova SN 2005hj (91T-like) at t = +5 days relative to the maximum light. Given a redshift of 0.084 (from the SDSS2) for its host galaxy, an expansion velocity of about 9500 km/s can be deduced from the Si II 635.5 absorption minimum; (3) The spectrum of PSN J09351328+5028219 is similar to that of a type IIn supernova SN 2008S at t = +17 - +20 days since explosion, showing a blue continuum with narrow Ha emission; (4) The spectrum of PSN J12393982+1124426 is similar to that of a type Ia supernova SN 2006S at t = -5 days. Given a redshift of 0.11-0.12 (from the SNID fit) for its host galaxy, an expansion velocity of about 11000-12000 km/s can be deduced from the Si II 635.5 absorption minimum; (5) The spectrum of PSN J08572629+4845195 is found to be consistent with that of a Quasar at a redshift of about 0.4, showing a blue continuum with strong and broad emission lines at 280.0 nm (due to Mg II), 488.0 nm and 660.0 nm.
