I revisited both the manga and anime but it was never really mentioned whether or not Chrollo directly hired Maha and Kalluto. My reason for my answer for #3 was based off Silva's rule as the Zoldycks' patriarchal figure to "stay away from the Troupe." I'm thinking, and I could be wrong, it must be a general rule that as long as they are taking assassination jobs as Zoldycks, every member of the family is advised/required to take stricter measures when dealing with the Troupe. Note that Zeno and Silva were also together. And as for a job coming from Chrollo himself (who's targeted by no other than Illumi's pops and gramps), Illumi had Maha and Kalluto for backup just in case things go sour. Whatever they do outside of the family's assassination business (e.g. Kalluto joining the Troupe) is outside of that rule.
