There are quite a few characters that are commonly paired with Bella in these fanfictions. For instance, Black Widow is a likely candidate. They could share their experiences as agents, their combat training, and their knowledge of the spy world. Then there's Agent Phil Coulson. His calm and collected nature could be a great foil to Bella's character, whether she's more impulsive or more by - the - book. And don't forget about Loki in some crossover fanfictions. His mischievous nature can create all sorts of chaos and interesting interactions when paired with Bella as a Shield agent.
I'm not entirely sure as it's a rather specific type of fanfiction. But perhaps themes of protection, friendship or adventure could be common, considering the 'shield' part might imply protection.
One popular 'Bella is a Shield Agent' fanfiction might be 'Bella's Shield Adventures'. It could explore her training as an agent, her relationships with other Shield members, and the missions she goes on. Another could be 'Bella in the Shadows of Shield' which might focus on her undercover work within Shield. And there could be 'Bella: The New Shield Agent' which perhaps details her rise as a rookie agent in Shield.

It's very unlikely that 'bella pussy is fist twilight fanfic' is a popular one. Popular Twilight fanfics often have titles that are related to the main characters' relationships, like Bella and Edward's love story, or some exciting plot twists within the Twilight world. This title is so unusual and hard to understand that it probably doesn't gain much popularity. Plus, if it contains some really unclear or unappealing language as it seems from the title, it would further reduce its chances of being popular.
Definitely not. The Twilight books are aimed at a wide audience, including younger readers. Fanfics that use such inappropriate descriptions are not in the spirit of the original series. It's better to explore fanfics that respect the characters and the story's essence without using such vulgar concepts.
Yes, there are some out there. You can start by looking on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Just search for 'Twilight Bella is a werecat' and you'll likely find a variety of stories with different takes on the concept.
