Abstract: We study 5-dimensional pseudo-Riemannian manifolds in the form of $h$-spaces $H_{32}$ of type $\{32\}$. A classification of $h$-spaces $H_{32,2}$ is given according to (non-homothetic) Lie algebras of infinitesimal projective and affine transformations, all projectively mobile metrics are found and the dimensions, basis elements and structural equations of the maximal non-homothetic projective Lie algebras operating in them are indicated.

Keywords: 5-dimensional pseudo-Riemannian manifold, $h$-space $H_ {32,2}$ of type $\{32\}$, system of partial differential equations, non-homothetical projective motion, Killing equation, projective Lie algebra.
