May several counties join together to form a multi-county CHSA?

No. The law does not allow multi-county consolidated human services agencies. It states: “In the exercise of its jurisdiction over commissions, boards, and agencies, the board of county commissioners of a county having a county manager pursuant to G.S. 153A-81 may” create a consolidated human services agency.[1] Other portions of the statute give particular powers or duties to the county manager—a delegation of authority that would pose significant implementation difficulties if the statute were construed to permit multi-county agencies.
