In addition, there might be some supporting characters within the Dark Angels' own ranks. Maybe an old veteran who imparts wisdom to a younger Dark Angel, or a tech - marine who plays a crucial role in maintaining the chapter's equipment during a difficult mission.
There could also be antagonists. In the Warhammer 40K setting, they might be various alien species like Orks or Chaos forces. These antagonists would provide the conflict that the Dark Angels have to face, and their interactions would drive the stories forward. For instance, a powerful Chaos Lord who challenges the Dark Angels' hold on a particular planet.
The main characters are likely to be the Dark Angels themselves. They are the focus of these short stories, so we can expect to see Space Marines from this chapter as the central figures.
Most likely, there will be Primaris Marines of the Dark Angels as main characters. Maybe some of their leaders or veterans.
In 'Darkness Falls: A Dark Angels Novel', the main characters would predominantly be Dark Angels. These could be the veteran warriors who have seen countless battles and hold the secrets and traditions of the chapter. There may be a young initiate who is on a journey to prove himself and discover the true nature of the Dark Angels. Additionally, there could be some characters from other races or factions that play important roles, perhaps an Inquisitor who has an interest in the Dark Angels and their affairs, or an enemy chaos lord who is trying to bring down the Dark Angels. The relationships and interactions between these characters would drive the plot forward in the complex world of Warhammer 40,000.
I'm not entirely sure, but likely it would feature characters from the Dark Angels chapter. Maybe the chapter master or some of the veteran sergeants.
Azrael is a main character. He is the Supreme Grand Master of the Dark Angels and plays a crucial role in leading the chapter.
We can't be certain without reading the novel, but it's common in these stories to have a central Primaris Marine who is on a journey of discovery. He might be mentored by an older, more experienced Dark Angel. There could also be antagonists, perhaps traitors or xenos who will test the Dark Angels' resolve and military might. And there might be some side characters, like the tech - marines who are responsible for maintaining the advanced wargear of the Primaris Marines.

As I haven't delved into 'Darkness Devours a Dark Angels Novel', it's difficult to say exactly who the main characters are. In Dark Angels stories, there are often leaders, librarians, and veteran warriors. It's likely that the main characters in this novel would be from among these types of Dark Angels. They could be on a quest to uncover a mystery or fighting against a great threat that is related to the 'darkness' mentioned in the title.
Since we don't know the exact 'City of Angels' short story, the main characters could be quite diverse. It could be an old man who has lived in the city all his life and has stories about seeing angel - like figures. There might also be a journalist who is trying to uncover the truth behind the city's reputation as the 'City of Angels'. Or it could be a family who moves to the city and has to deal with the challenges and the possible angelic interventions in their new life there.
One of the main characters could be a powerful Dark Hunter with extraordinary skills. He might be the one who often takes on the most dangerous missions.
Susannah is another main character. She has unique abilities and her own backstory that is likely explored in the short stories. Her relationship with Roland and the others is complex, and the short stories might show different aspects of how they interact and depend on each other.
