Generally, although depending on the exercise you may want more or less volume.
As very general and vague recommendations I have seen it reccommended at 40-50 total jumps (this is for depth jumps and drops) for beginning athletes over a week and 80-120 for advanced athletes over a week.
There's tons of ways to do it, people have had a lot of success doing complex-training where heavy lifts are alternated with plyometrics.
Here's an example of that (this is from the CT article: "Power Continuum II", look it up because it has some good info):
A1. Front squat
3-5 reps at 80-85%
2 minutes before A2
A2. Speed squat (with bands if available)
3 reps at 45-55%
2 minutes before A3
A3. Jump squat
10 reps at 20-30% of max squat
2 minutes before A4
A4. Depth jumps
3 minutes before starting a new circuit
He recommends doing 2-5 circuits depending on preparedness.
