Yes, you still can get one. Nominations are sort of a large jigsaw puzzle. It is part Science and part Art. So in this scenario if your assumption is true that your friend received the principal nom, if he is 3Q, the chances are pretty high he will receive this appointment. No guarantees. USNA is different than USMA and USAFA, as principal noms are not a guarantee if 3Q. The US Code for USNA is written slightly different. It is rare for a candidate who is 3Q with a principal to not get an appointment but there is no guarantee. As long as you are one of the 10 on the nomination slate, regardless of the type of slate submitted (ranked, unranked, etc), you qualify to be put on the NWL. Plug in NWL in the search feature and there is lots of good info on here about that. The Art of Noms for the admissions board is they will move people around to different slates that they are qualified for. When appointees actually realize who appointed them at some point Plebe year it is sort of surprise who they are ultimately are charged to. Hang in there, I have seen as many as 6 kids from 1 high school receive appointments. Northern VA has dozens of appointments a year, because that area has tons of presidential nomination candidates and those who are highly qualified and come of the NWL.
