You could do that without me writing it out, but as you're first becoming familiar with this kind of thing, it's good to see it all together. You'll probably end up doing some combinations of things you wouldn't get to if you were just working from memory.
The top portion of the page just gives you the basic rhythm and foundational interpretations of it— there's no special need to practice them, but take a moment to study them and figure out how they relate to the base rhythm. Learn each of the practice patterns individually, then play all possible combinations of them:
A-B, A-C, A-D, through A-O
B-C, B-D, B-E, through B-O
C-D, C-E, etc
For each combination, play each measure once or twice:
Practice each sequence above many times, of course. Take care with the transitions between patterns— get them right in the practice room and you'll have better control when improvising on stage. Don't be too hihat-centric in your practicing— use all the cymbals. Pattern C and the hand unisons in patterns L and N can be played on cym/snare or toms/snare. Move patterns K and O around the drums.
