  Exact BPS solutions of multi-walls are obtained in five-dimensional
supergravity. The solutions contain 2n parameters similarly to the moduli space
of the corresponding global SUSY models and have a smooth limit of vanishing
gravitational coupling. The models are constructed as gravitational
deformations of massive T^*CP^n nonlinear sigma models by using the off-shell
formulation of supergravity and massive quaternionic quotient method with
U(1)*U(1) gauging. We show that the warp factor can have at most single
stationary point in this case. We also obtain BPS multi-wall solutions even for
models which reduce to generalizations of massive T^*CP^n models with only
U(1)^n isometry in the limit of vanishing gravitational coupling. At particular
values of parameters, isometry of the quaternionic manifolds is enhanced.
