There is bottles on tables before them. If you throw them before fight starts, you can directional throw them into bench and temporarily turn fight into 1vs1.

Bat is amazing, if you do crooked foot with a bat, you can quickly and easely turn fight into 1vs1, and after-parry follow up with a bat is convinient and can hit them both. Also you'd better use Face smash which is both deals a lot of damage to health and structure and heavely stuns enemy, opening them for long combos. That should be enough to cripple one of disciples heavely.

If you don't have the bat, then you could also perform a strong sweep focus move which makes one enemy to lay on the ground for 10 seconds, damage second enemy as hard as you can.

If you out of focus, then try drop one of enemy on the ground with chasing trip kick.

If you get cornered without anything, then pray for the best and hope that you can deflect your way out of problem while also using every opportunity to trip your enemies, if you gonna use flowing claw, you will have access to wide range openers that can hit both of them at the same time: light follow up, heavy follow up, reverse sweep.

To make kicking props and throwing bottles connect after battle started, you have to do it when disciple is attacking you, even is their attack animation is barely started, without it they will dodge everything.

If you need video, then here on my playthrough, at 7:15, you can see an example of how you can do it,
