The principal positions of non-Hermitian models with $\gamma_5$-mass extensions are formulated. A simple estimation for determination maximal permissible fermion mass value $M$ is produced. It is shown that a zone of PT-symmetry includes as ordinary and exotic particles. Paradox distinguish of inertial and gravitation particle's properties for "exotic" particles is shown. It is found that unusual properties of the exotic particles allow to consider their as possible candidates in structure of dark matter.
