Yes, there are. You can find some on fanfiction websites like Archive of Our Own. There are various interpretations of female musketeers in these stories, often with strong, independent female characters taking on the swashbuckling adventures in the musketeer world.
One common theme is gender equality. Since it's about female musketeers, it often shows them fighting against the gender norms of their time. Another is friendship. Just like in the original musketeer stories, the female musketeers form strong bonds with their comrades. Adventure is also a big theme as they go on various quests and missions.
The first place I would recommend is AO3. It has a tagging system that makes it easy to search for specific types of fanfiction like female musketeer ones. Another option could be to search on Tumblr. Although Tumblr is more of a social media platform, there are many fanfiction writers who post their works there, and you can use relevant hashtags to find the female musketeer fanfiction you're looking for.

One great 'musketeer girl familiar of zero fanfic' could be 'The Musketeer Girl's Adventure in Familiar of Zero World'. It has an interesting plot where the musketeer girl gets involved in the complex magic and political situations in the Familiar of Zero universe.
The combination of the musketeer theme and the Familiar of Zero setting makes it unique. A musketeer girl brings a different kind of combat style and honor code compared to the normal characters in Familiar of Zero. It adds a new flavor to the story.
The title of the Royal Musketeer in Journey 2S was obtained by completing specific missions. This quest required the player to complete the quest at a specific NPC in the game. The specific requirements included defeating a certain number of enemies, completing a specific quest, obtaining a specific item, and so on. After completing the mission, the player would be awarded the title of Royal Musketeer and receive some additional attribute bonuses in the game.
The main differences are in their expressions and some minor details of personality. In the manga, Deku might seem a bit more intense, while in the anime, he's sometimes presented a bit softer.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
His friends could come to the rescue. Bakugo, for instance, might use his explosive power to break into Toga's hideout. He's always been competitive with Deku, but he also cares about him deeply.
