If those breaks in OP''s itinerary represent separate tickets, even if in the same PNR, then US-origin or destination tickets will apply the rule above and the other ticket(s) will apply local rules to those tickets.
Fist of all, a UA issued ticket cannot have more than four segments, so five segments is at least two tickets.
Second, UA website, always shows me baggage allowance as per check-in carrier rules, and premier additional allowance is not shown for partner carriers. Is UA website wrong?
Would a partner airline really follow UA baggage rules, instead of their own, at check-in? Seems like it would be hard for the agents to keep track of different airline rules.
