   • OP warned about not having an attempt at a solution

   1. The problem statement, all variables and given/known data
   
   δ(z*-z0*)δ(z+z0)=?
   δ(z*+z0*)δ(z-z0)=?
   
   where 'z' is a complex variable 'z0' is a complex number
   Formula is just enough, derivation is not needed.

   The Dirac delta is a distribution, not a number or a function from one number field to another.
   The product of distributions is not in general well defined, see here. You can multiply a distribution by a smooth function, but not in general by another distribution.
   So the expressions above do not have a clear meaning. They are not well-defined.
