We study five-dimensional 
gauged supergravity coupled to five vector multiplets with compact and non-compact gauge groups 
and 
. For gauge group, we identify
vacua with and 
symmetries and analytically construct the corresponding holographic RG flow interpolating between these critical points. The flow describes a deformation of the dual 
SCFT driven by vacuum expectation values of dimension-two operators. In addition, we study 
geometries, for 
being a two-sphere 
or a two-dimensional hyperbolic space 
, dual to twisted compactifications of SCFTs with flavor symmetry SU(2). We find a number of 
solutions preserving eight supercharges for different twists from 
and 
gauge fields. We numerically construct various RG flow solutions interpolating between
critical points and these geometries in the IR. The solutions can also be interpreted as supersymmetric black strings in asymptotically space. These types of holographic solutions are also studied in non-compact gauge group. In this case, only one
vacuum exists, and we give an RG flow solution from this to a singular geometry in the IR corresponding to an non-conformal field theory. An solution together with an RG flow between this vacuum and the
are also given.
