> Aww. Is there any plans to add any?

No, sorry. There's only 1 more girl planned, and she's on the curvier side.
In general, too small/flat boobs are unfortunately considered an indicator of a character potentially being underage by sites like Patreon, and there are no exact minimum size/depth values defined by them so as a dev you're somewhat at the whim of whoever checks your work.
Which is of course objectively bollocks, since biologically, flat areolas would be a much more accurate indicator of maturity than chest size, as the latter can vary greatly by nature and is heavily body-fat-percentage-influenced on top of that.

With that being said, there'll be a new side-project soon with a tall but relatively flat-chested girl, where all girls (well, at least their lewd scenes) are avoidable, and some of the later side-girls will also take it as far with the flatness as we feel we can go without repercussions.
It's going to be a while, though.

> And is it possible to only go for specific characters and ignore the others?

Well, sort of.
Not if you play the game 'properly' from the beginning, but it has a "Skip to" main menu option that lets you skip to a later point in the game.

If you jump to the beginning of chapter 2, you can watch the redhead's story scenes from Chapter 1 in her gallery and skip the 3 other original maids, and focus on the white-haired Ch2 maid, if her chest is small enough for you.

The sidegirl I mentioned is a bit later in Chapter 2, you can use the "Skip to" again and jump to the point "after Mary's Ch2 story" if you want to avoid the other girls as much as possible, then go to the mansion entrance during a workday afternoon, there should be a "?" icon, clicking that takes you to her story scene (she's the current cover girl).
