We present B, V, Rc and Ic light curves of four contact binary systems and one semi-detached system. New observations confirm and revise the short-period (0.22–0.25d) of the systems and that all the couple of stars belong to the spectral type K. In J105924 and J164349 a third light was found while the shape of the light curves of four systems (excluding J105924) suggest the presence of inhomogeneities on the surface of one component which confirms that the systems are active. Also they are observed at low orbital inclination i∈ (41°, 62°). Temperature differences range is ΔT∈(4,640)K and mass ratios q∈(0.20, 0.75). Absolute parameters are estimated using statistical diagrams. Systems follow the general pattern of the relative subtype of W Ursae Majoris systems. The sum of the component masses of four systems is below the mass limit of 1.0 – 1.2M☉ assumed for the known contact binary stars, this tells us that they belong to the class low mass contact binaries.
