1 Chronicles 24 describes how King David, along with Zadok and Ahimelech, divided the priests descended from Aaron into 24 courses (or divisions) to serve in the temple. The verse you quoted, "the fifteenth to Bilgah, the sixteenth to Immer," simply identifies the specific priestly families that were assigned to the 15th and 16th courses, respectively:
Bilgah: This was the family or house assigned to the 15th course.
Immer: This was the family or house assigned to the 16th course.
Essentially, it's a record-keeping detail, like a roster or schedule, stating which family was responsible for priestly duties during those specific periods of the temple service year. It's part of the organizational structure that David established for the temple rituals.
