Single crystals of Frank-Kasper compounds RTM$_2$Al$_{20}$ (R = Eu, Gd andLa; TM = V and Ti) were grown by self-flux method and their physical propertieswere investigated through magnetization ($M$), magnetic susceptibility($\chi$), specific heat ($C_P$) and electrical resistivity ($\rho$)measurements. Powder x-ray diffraction studies and structural analysis showedthat these compounds crystallize in the cubic crystal structure with the spacegroup $Fd\overline{3}m$. The magnetic susceptibility for the compoundsEuTi$_2$Al$_{20}$ and GdTi$_2$Al$_{20}$ showed a sudden jump below the N{\'e}eltemperature $T_N$ indicative of plausible double magnetic transition. Specificheat ($C_P$) and electrical resistivity ($\rho$) measurements also confirm thefirst-order magnetic transition (FOMT) and possible double magnetictransitions. Temperature variation of heat capacity showed a sharp phasetransition and huge $C_P$ value for the (Eu/Gd)Ti$_2$Al$_{20}$ compounds Fullwidth at half-maximum (FWHM) $<$ 0.2 K) which is reminiscent of a first-orderphase transition and a unique attribute among RTM$_2$Al$_{20}$ compounds. Weobserved clear anomaly between heating and cooling cycle in temperature-timerelaxation curve for the compounds GdTi$_2$Al$_{20}$ (2.38 $K$) andEuTi$_2$Al$_{20}$ (3.2 $K$) which is indicating a thermal arrest due to thelatent heat. The temperature variation of $S_{mag}$ for GdTi$_2$Al$_{20}$saturates to a value $0.95R\ln8$ while the other magnetic systems exhibitedstill lower entropy saturation values in the high temperature limit.Resistivity measurements showed that all the samples behave as normal Fermiliquid type compounds and $\rho(T)$ due to electron-phonon scattering followsBloch-Gr$\ddot{\textrm u}$neisen-Mott relation in the paramagnetic region.
