Magnetic properties of polycrystalline thin films of chromium chalcogenide spinels (CdCr_{2}Se_{4} lightly doped with indium and CdCr_{2x}In_{2-2x}Se_{4}) were studied. The ferromagnetic (FMR) and spin-wave resonance (SWR) techniques were used to investigate the temperature dependences of both the spin-wave stiffness constant D and the saturation magnetization M_{s}. The resonance spectra were recorded in the temperature range extending from 4.2 K to 300 K. The influence of indium concentration on M_{s}(T) and D(T) was studied. It was shown that lightly doped samples (In/Cd < 1% at.) exhibited the ferromagnetic ordering with M_{s}(T) and D(T) being the linear functions of T^{3/2} and T^{5/2}, respectively. Higher concentration of indium produced the reentrant transition and spin-glass state of magnetic ordering in CdCr_{2x}In_{2-2x}Se_{4}. The temperature dependence of M_{s} was also found from the FMR data for these two magnetic phases.
