  In Ref. \cite{Goyal:2019vsw}, we had considered simplified dark matter models
interacting gravitationally with the Standard Model particles in a
Randall-Sundrum frame work where models are considered with non-universal
couplings. In the top-philic graviton model the right-handed top quarks are
taken to interact strongly with the gravitons and in the lepton-philic model,
we assume that only the right-handed charged leptons interact strongly with the
gravitons. We extend the study to include not only the scalar, vector and
spin-1/2 fermions but also spin-3/2 fermionic dark matter. We find that there
is a large parameter space in these benchmark models where it is possible to
achieve the observed relic density consistent with the direct and indirect
searches, which are also consistent with the data from Large Hadron Collider.
