No it's Jason
Jason is reunited with Thalia in Chapter 49 of "The Lost Hero" by Rick Riordan.
No, in "The Lost Hero" by Rick Riordan, the character Jason does know his name. However, he has lost his memory and is struggling to remember his past and how he ended up at a wilderness camp.
Jason and Thalia had the same mother who was a movie star actress who went by the surname Grace

There are three main characters, Jason, Piper, and Leo. But I think that Jason is the protagonist because he changes as he regains his memory in the end of the book, but I'm not sure.

Neptune is the Roman equivalent of Poseidon, so presumably it will be similar to The Lost Hero, but with Percy at the Roman Camp instead of Jason at the Greek one.
IN the Lost Hero There are three new main characters Piper,Jason, and Leo but It is focused of Jason because of the plotline I would like to add that that the perspective in wich the story is told is changed every 2 chapters
In the new series ( The Lost hero) he has a son called Jason.
Basically in their dreams or events in their past
He has to deal with having no memory and trying to save his new friends
