Mayeb this helps answer?
Q:
Can Garm Bel Iblis bring in an Antarian Ranger or Yuuzhan Vong Ossus Guardian into a New Republic or Rebel squad through his Reinforcements?
A:
Yes to a New Republic squad, both these characters are allowed in New Republic squads. No to a Rebel squad. The faction is not adjusted until after the character is legally added to the squad and neither of these characters
is allowed in a Rebel squad.
Edit: So, to answer your question, it appears "Yes" for both the characters you listed.
