Intervals above 8 (10 and 12) are the compound intervals. 10 is a major or minor tenth (a third plus an octave) and 12 is a perfect twelfth (a perfect fifth plus an octave).
The rhythm of this counterpoint will be in 8th notes. That's what we call a 2nd species counterpoint. Notice that the intervals are all consonances (1, 3, 5, 6, 8, 10, and 12) because in the 2nd species no dissonant intervals (tritones, 2nds, 7ths etc.) are allowed.
In measure 7 there is a 6 with #. This means that we have a cadence in the key of D major here and we need a second sharp - that's C#.
