  We present the results of the XMM-Newton observations of five hard X-ray
emitters: IGR J08262-3736, IGR J17354-3255, IGR J16328-4726, SAX J1818.6-1703,
and IGR J17348-2045. The first source is a confirmed supergiant high mass X-ray
binary, the following two are candidates supergiant fast X-ray transients, SAX
J1818.6-1703 is a confirmed supergiant fast X-ray transient and IGR J17348-2045
is one of the still unidentified objects discovered with INTEGRAL. The
XMM-Newton observations permitted the first detailed soft X-ray spectral and
timing study of IGR J08262-3736 and provided further support in favor of the
association of IGR J17354-3255 and IGR J16328-4726 with the supergiant fast
X-ray transients. SAX J1818.6-1703 was not detected by XMM-Newton, thus
supporting the idea that this source reaches its lowest X-ray luminosity
(~10^32 erg/s) around apastron. For IGR J17348-2045 we identified for the first
time the soft X-ray counterpart and proposed the association with a close-by
radio object, suggestive of an extragalactic origin.
