Does anyone has proof of radial momentum operator as an Hermitian operator? Thanks.

By the radial momentum operator you mean the momentum conjugate to $$r$$? Sandwich it between two wavefunctions, integrate by parts, and all should work out. Remember the integration measure contains a factor of $$r^2$$.
