Who will be my teammates

Okay, your pilots are determined by your choice of weither to embark on the MSF, NESF, Triada, Inoco, or Alex mission lines...

These are the pilots you will get no matter what:
Hero
Ternie
Greyhair
Kalem
Joseph - He temporarily joins your party for the artifact expedition, and leaves after that.

If you go NESF (going to the mercenary base), you will get:
Che - You get him when you have to fight off a massive pirate fleet while doing one of Alexandra's missions.
Alexandra - Shes the one who comes to the rescue you after you rescue Ternie

If you go MSF (going to the Patrol headquarters), you will get:
Validol - You get an optional mission to find him, I recommend you take it.
Viper - Shes the one who rescues you after you rescue Ternie
Adm. Trump - If you decide to side with Trump rather than Viper, Viper leaves and you get Trump in her place

If you go Triada (going to the Triada Headquarters), you will probably get (I never played the Triada line, so I donno):
Aja
Alice

If you go Inoco (Betraying triada after given the option by Inoco), which you probably wont because its so badly bugged:
Jana
SAM

If you go Alex (if you fail a mission):
Alex
Cleric

Ternie didn't die in my finished NESF/Corsair campaign. Just started MSF and any info regarding her death 'd be nice? I don't really want to lose her

I played NESF, Alex, and MSF Campaigns and did not lose Ternie in any of them...

Just before that, you will be able to recruit a guy named Silverlight (I will have to double to check to confirm, once I got home).

You probably mean greyhair... there is no such thing as a pilot named silverlight.
