Structure a semi-private training session..HOW?

I've been coaching for almost 5 years now in person and online. I'm looking to increase my revenue and have been learning about semi-private training. Does anyone else do this? How do you structure the session? Or how would you with the next example.

For instance....I have semi-private training classes starting first week of February. 3 people. All different goals/fitness levels. I plan on doing a group warm up and group cooldown (non negotiable as I want this to be a community time), but everything else I'm a little lost. Do I do blocks of time with 2-3 exercises per person?

Edit: They will have different programs
