If the primal problem has maximize objective function, non-negative variables, and 4 constraints, each of which is $\leq$ type, then the dual problem will have 4 variables and all of them will be non-negative.

In the dual problem, each constraint of the primal problem corresponds to a variable, and since all primal constraints are of the $\leq$ type, all dual variables will indeed be non-negative.
