  Lepton masses and mixing angles via localization of 5D fields in the bulk are
revisited in the context of Randall-Sundrum models. The Higgs is assumed to be
localized on the IR brane. Three cases for neutrino masses are considered: (a)
The higher dimensional LH.LH operator (b) Dirac masses (c) Type I see-saw with
bulk Majorana mass terms. Neutrino masses and mixing as well as charged lepton
masses are fit in the first two cases using $\chi^2$ minimisation for the bulk
mass parameters, while varying the $\mathcal{O}(1)$ Yukawa couplings between
0.1 and 4. Lepton flavour violation is studied for all the three cases. It is
shown that large negative bulk mass parameters are required for the right
handed fields to fit the data in the LH LH case. This case is characterized by
a very large Kaluza-Klein (KK) spectrum and relatively weak flavour violating
constraints at leading order. The zero modes for the charged singlets are
composite in this case and their corresponding effective 4-D Yukawa couplings
to the KK modes could be large. For the Dirac case, good fits can be obtained
for the bulk mass parameters, $c_i$, lying between 0 and 1. However, most of
the `best fit regions' are ruled out from flavour violating constraints. In the
bulk Majorana terms case, we have solved the profile equations numerically. We
give example points for inverted hierarchy and normal hierarchy of neutrino
masses. Lepton flavor violating rates are large for these points. We then
discuss various minimal flavor violation (MFV) schemes for Dirac and bulk
Majorana cases. In the Dirac case with MFV hypothesis, it is possible to
simultaneously fit leptonic masses and mixing angles and alleviate lepton
flavor violating constraints for Kaluza-Klein modes with masses of around 3
TeV. Similar examples are also provided in the Majorana case.
