Page 13 cover Recruiting Grunts/NPCs. You get 1 Recruiting Point per point of Star Rep so figure 5. That can get you a the most 5 recruits, often less. On the PEF Resolution Table (page 71) you'll see the most you can run into is 2 more than your group. So if you have your Star and 5 Grunts (NPCs) for 6 the most you'll meet is 8.
Hope this helps.
