Context. The ESO public survey VISTA Variables in the Via Lactea (VVV) has contributed with deep multi-epoch photometry of the Galactic bulge and the adjacent part of the disk over 526 sq. deg. More than a hundred cluster candidates have been reported thanks to this survey. Aims. We present the fifth article in a series of papers focused on young and massive clusters discovered in the VVV survey. In this paper, we present the physical characterization of five clusters with a spectroscopically confirmed OB-type stellar population. Methods. To characterize the clusters, we used near-infrared photometry (J, H, and K-S) from the VVV survey and near-infrared K-band spectroscopy from ISAAC at VLT, following the methodology presented in the previous articles of the series. Results. All clusters in our sample are very young (ages between 1-20 Myr), and their total mass are between (1.07(-0.30)(+0.40)) x 10(2) M-circle dot and (4.17(-2.08)(+4.15)) x 10(3) M-circle dot. We observed a relation between the clusters total mass M-ecl and the mass of their most massive stellar member m(max), for clusters with an age <10 Myr.
