In all honesty, it sounds more complex than it is...
The first option is always to give the RB the ball on the run play.
Then if the read takes the run away, the QB then pulls the ball and transitions to his secondary read, which is typically a flat defender/outside linebacker.
Reads then work out from inside out or low to high on which receiver to throw the ball to.
If it is a trips set where there are 3 receivers to that side, options 2, 3, and 4 are those 3 receivers.
Option 5 is a checkdown to a crossing backside receiver on a slant or dig route.
Option 6 is for the QB to run the ball himself.
Rarely do you see an offense at the high school level of carrying it out past first 2 to 3 options. Most high school QBs will get the first read on the give/keep on the run play. Then their second read/option is the first receiver. After that, they typically tuck and run and never get to the rest of the options
