The exact solution of a system of bilinear identities derived in the first part of our work [1] for the case of real Grassmann-odd tensor aggregate of the type (S,Vμ,Tμν⁎,Aμ,P) is obtained. The consistency of the solution with a corresponding system of bilinear identities including both the tensor variables and their derivatives (S˙,V˙μ,T˙μν⁎,A˙μ,P˙) is considered. The alternative approach in solving of the algebraic system based on introducing complex tensor quantities is discussed. This solution is used in constructing the mapping of the interaction terms of spinning particle with a background (Majorana) fermion field ΨMαi(x). A way of the extension of the obtained results for the case of the Dirac spinors (ψDα,θDα)(ψDα,θDα) and a background Dirac field ΨDαi(x), is suggested. It is shown that for the construction of one-to-one correspondence between the most general spinors and the tensor variables, we need a four-fold increase of the number of the tensor ones. A connection with the higher-order derivative Lagrangians for a point particle and in particular, with the Lagrangian suggested by A.M. Polyakov, is proposed.
