  We have used photometry from the WASP-South instrument to identify 5 stars
showing planet-like transits in their light curves. The planetary nature of the
companions to these stars has been confirmed using photometry from the EulerCam
instrument on the Swiss Euler 1.2-m telescope and the TRAPPIST telescope, and
spectroscopy obtained with the CORALIE spectrograph. The planets discovered are
hot Jupiter systems with orbital periods in the range 2.17 to 5.75 days, masses
from 0.3M$_{\rm Jup}$ to 1.2M$_{\rm Jup}$ and with radii from 1R$_{\rm Jup}$ to
1.5R$_{\rm Jup}$. These planets orbit bright stars (V = 11-13) with spectral
types in the range F9 to G4. WASP-126 is the brightest planetary system in this
sample and hosts a low-mass planet with a large radius (0.3 M$_{\rm Jup}$ ,
0.95R$_{\rm Jup}$), making it a good target for transmission spectroscopy. The
high density of WASP-129 A suggests that it is a helium-rich star similar to
HAT-P-11 A. WASP-133 has an enhanced surface lithium abundance compared to
other old G-type stars, particularly other planet host stars. These planetary
systems are good targets for follow-up observations with ground-based and
space-based facilities to study their atmospheric and dynamical properties.
