If Aldo loses against Conor, and gets destroyed in the process. Will Aldo get an immediate rematch? 
gets destroyed?? maybe not
any other way, yes
Nah, too many other fights people want to see. Mendes would probably play more into the build up than Aldo has as well. Rest assured the rematch would happen though.
Which of course sets up the trilogy.
I'd like to say that if he somehow gets totally destroyed he wouldn't, but Barao was supposed to get an immediate title fight, so Aldo probably would too. 
I hope not but the UFC loves their rematches so he probably will.
If aldo loses no but if Connor loses I heard a rumor there buying out Jose's contract and giving mcgregor the belt anyway
I don't think they'd want to take the chance that Aldo might beat him in the rematch but how can you deny Aldo.
Yes. They will either do an instant rematch or give him the winner of Do Bronx-Holloway. They'll keep Conor away from Mendes and Edgar as long as humanly possible. They'll probably make those two fight actually.
Rematch in Dublin or Cardiff would be a monster. Stadium would sell out.
caposa -Those two should be fighting each other anyways.
