At the quantum scale (in an atom/nucleus), the "size" of electrons or any other fundamental particles loses its meaning because these "particles" behave like waves or wave packets. So "size" becomes kind of "squishy". When we model electrons as classical particles, they are effectively sizeless point particles. Anyway, there seem to be a limit to how small things can be which is about 1.6 × 10−35 m - Planck's length.

If by smaller you mean lighter then yes! For example, the neutrino is much lighter than the electron. In fact, the electron neutrino (just one of many types) has a mass of about 2.2 eV. Compare that to the mass of an electron, a whopping 510,998 eV!
