The name Carajá was applied at least twice by Neiva. The first use was for a 1984 PT6A-powered EMB-821 Navajo variant (whose wing and undercarriage design were originally to be incorporated into what finally became the Tucano turboprop trainer).

The N.721 Caraja was a turboprop N.621 Universal derivative (although there were other modifications - stronger wings, enlarged fin, and changes to landing gear and windscreen.

The EMB-311 was simply a turboprop version of the EMB-301. The COIN study you refer to was referred to as COIN-X. As mentioned, this was a straightforward adaptation of the Caraja (but does anyone know if N.721B refers to COIN-X or was just a further Caraja design phase?).
