  We present timing and spectral analysis of a sample of seven hard X-ray
selected Cataclysmic Variable candidates based on simultaneous X-ray and
optical observations collected with XMM-Newton , complemented with Swift/BAT
and INTEGRAL/IBIS hard X-ray data and ground-based optical photometry. For six
sources, X-ray pulsations are detected for the first time in the range $\rm
\sim296-6098\,s$, identifying them as members of the magnetic class. Swift
J0927.7-6945, Swift J0958.0-4208, Swift J1701.3-4304, Swift J2113.5+5422, and
possibly PBC J0801.2-4625, are Intermediate Polars (IPs), while Swift
J0706.8+0325 is a short (1.7 h) orbital period Polar, the 11$^{\rm th}$ hard
X-ray selected identified so far. X-ray orbital modulation is also observed in
Swift J0927.7-6945 (5.2 h) and Swift J2113.5+5422 (4.1 h). Swift J1701.3-4304
is discovered as the longest orbital period (12.8 h) deep eclipsing IP. The
spectra of the magnetic systems reveal optically thin multi-temperature
emission between 0.2 and 60 keV. Energy dependent spin pulses and the orbital
modulation in Swift J0927.7-6945 and Swift J2113.5+5422 are due to intervening
local high density absorbing material ($\rm N_H\sim10^{22-23}\,cm^{-2}$). In
Swift J0958.0-4208 and Swift J1701.3-4304, a soft X-ray blackbody (kT$\sim$50
and $\sim$80 eV) is detected, adding them to the growing group of "soft" IPs.
White dwarf masses are determined in the range $\rm \sim0.58-1.18\,M_{\odot}$,
indicating massive accreting primaries in five of them. Most sources accrete at
rates lower than the expected secular value for their orbital period. Formerly
proposed as a long-period (9.4 h) novalike CV, Swift J0746.3-1608 shows
peculiar spectrum and light curves suggesting either an atypical low-luminosity
CV or a low mass X-ray binary.
