Since I don't know the details of the story, it's hard to say exactly. But they could be ordinary suburban residents who find themselves in extraordinary situations due to the 'war' situation. Maybe a local shopkeeper, a stay - at - home parent, or a group of teenagers.
It could be that the main characters are those who are caught in the middle of the conflict in the suburbs. They might be people with different beliefs and goals. For instance, there could be an environmentalist trying to protect the suburb's natural areas during the chaos, while on the other hand, there could be a developer who sees the situation as an opportunity to make changes to the area. Their clashes and interactions could form the core of the story.
It could be about the chaos and struggles in a suburban area that are somehow related to a war - like situation. Maybe it's about conflicts between different groups in the suburbs, or the impact of external events that bring a sense of war to the otherwise peaceful suburban setting.
You might be able to find it on popular streaming platforms like Netflix or Amazon Prime Video.
I'm not familiar with the 'Street Grace Suburban Horror Story', but it's likely that the main characters are those who live on or near Street Grace. It could be a group of teenagers who are curious about the strange happenings on the street and end up getting caught in the middle of the horror. Or perhaps an old man who has lived on the street for a long time and has some knowledge about the origin of the horror but is too afraid to tell anyone until the events force him to.
The main character is surely the American boyfriend. And there must be his love interest, perhaps a girl from the same suburban area or someone who has a connection to that suburban place.

Marcus Fenix is one of the main characters. He's a tough and skilled soldier in the fight against the Locust.
The main characters are likely to be the ones who have been most affected by the war in its final stages. This could include people who have lost their homes, families, or livelihoods. Maybe a young man who is trying to protect his sister and mother, or an old woman who has seen her entire neighborhood destroyed and is now relying on her wits to stay alive.
Nicol Bolas is a main character, being the big bad. Then there are Planeswalkers like Chandra Nalaar, Jace Beleren. Liliana Vess also plays an important role. There are others as well, but these are some of the key figures in the War of the Spark story.
Marcus Fenix is one of the main characters. He's a key figure in the COG's fight against the Locust Horde. Dom Santiago is also important. He's Marcus' friend and comrade. Colonel Hoffman plays a significant role in leading the COG forces as well.
The main characters in the 'War of the Monsters' story are, of course, the monsters. There could be a slithering serpent - type monster that can move at lightning speed. There might also be a hulking, bear - like monster with a thick hide. These monsters are the focus as they battle each other. Their actions drive the story forward. Their interactions with each other, whether it's a fight or a temporary alliance, are what make up the main events of the story.
