Based on the Schengen Area rules for international travel:
Lisbon (Portugal) - Immigration clearance is required here. Since Lisbon is the first point of entry into the Schengen Area (and Brazil is outside Schengen), the passenger must clear immigration (passport control) in Lisbon. This is standard for all non-Schengen arrivals.
Paris (France) - No immigration clearance is needed. After clearing immigration in Lisbon, the onward flight to Paris is considered a domestic Schengen flight (no border checks within Schengen).
