13\15 and 14\15 are seventh-like, with 13\15 as a minor 7th and 14\15 as a major 7th. This also means that if it exists, 13\15 will likely be your guy for seventh chords, as dominant sevenths are the default.

12\15 is in a weird case; I tend to call it the "wolf seventh" though, as it has the same interval with the wolf fifth (8\15) that the wolf fifth has with the minor third (4\15).
12\15 is in a weird case; I tend to call it the "wolf seventh" though, as it has the same interval with the wolf fifth (8\15) that the wolf fifth has with the minor third (4\15). However, it is "technically" a harmonic seventh, and forms harmonic seventh chords.
 
Technically, in chords, any seventh can serve as the new note on top of a three-note chord. However, I think it best to, if possible, stick to the wolf seventh for wolf chords, and the minor seventh for non-wolf chords.
