Since I haven't read the 'Good Shepherd' novel, I can't name the exact characters. But often in a story about a shepherd, you might expect to find characters such as the shepherd himself. He could be a young man full of hope and dreams, trying to take care of his flock. There may also be antagonists, like a wolf that threatens the flock, or a greedy landowner who tries to take over the shepherd's grazing land. And of course, there could be friends or family members of the shepherd, like his father who taught him the ways of shepherding, or a childhood friend who helps him in times of trouble.
I'm not entirely sure as I haven't read the 'Good Shepherd' novel specifically. However, generally in a novel, main characters are those who drive the plot forward. They could be a protagonist, perhaps a shepherd who is the central figure, and there might be other supporting characters like the people in the shepherd's village, or those he meets on his journey.
