The orthogonal automorphism groups $\operatorname{Ortaut}A$ for $\mathbb Z_3$-orthograded quasimonocomposition algebras $A$ of dimension $9$ satisfying the conditions $\dim A_0=1$, $A_1A_2=0$

In [1], the author has found all orthogonal non-isomorphic $\mathbb Z_3$-orthograded quasimonocomposition algebras $A=A_0\oplus A_1\oplus A_2$ satisfying the conditions $\dim A=9$, $\dim A_0=1$, and $A_1A_2=0$. In this paper we construct their orthogonal automorphisms groups.
