  The generic non-extremal Kerr-Newman black holes are holographically dual to
hidden conformal field theories in two different pictures. The two pictures can
be merged together to the CFT duals in general picture that are generated by
$SL(2,\mathbb{Z})$ modular group. We find some extensions of the conformal
symmetry generators that yield an extended local family of $SL(2,\mathbb{R})_L
\times SL(2,\mathbb{R})_R$ hidden conformal symmetries for the Kerr-Newman
black holes parameterized by one deformation parameter. The family of deformed
hidden conformal symmetry for Kerr-Newman black holes also provides a set of
deformed hidden conformal generators for the charged Reissner-Nordstrom black
holes. The set of deformed hidden conformal generators reduce to the hidden
$SL(2,\mathbb{R})$ conformal generators for the Reissner-Nordstrom black hole
for specific value of deformation parameter. We also find agreement between the
macroscopic and microscopic entropy and absorption cross section of scalars for
the Kerr-Newman black hole by considering the appropriate temperatures and
central charges for the deformed CFTs.
