Three of the five enemies are strictly physical attackers. OronJoker is randomized because that's the entire point, and ArmoredKori's Dispose is brutal, but otherwise, a team designed to mitigate physical damage is going to do well. Especially since literally everyone except certain OronJokers doesn't have any AoE other than Geomancy, and Caazan's Geomancy is dragged down by having Lancer stats with its shitty MA.
Akashachi is vulnerable to status effects unless he rolls a bunch of immunity equipment, and CCing him is the specific intent of the fight; that's why I throw him in your face right out of the gate and force you to kill him first only to immediately be punished for it. Blind (against an evasive unit in his face), Sleep, Stop, Slow, Don't Move, and Don't Act are great ways to keep him under control.
Caazan, NinjaWeazel, and OronJoker can all be killed immediately, and should be. NinjaWeazel specifically: while he comes with Abandon, he has no shield, and with random equipment, isn't super likely to have a lot of EV. Even if he does, magical or unavoidable attacks will make quick work of him, since he has no counterattacks and no recovery options. A Geomancer/Ninja isn't the easiest thing in the world to take out, but you're not expected to be able to beat this fight until you can match the loadouts of the generic enemies in it. Your own Geo/Ninja or equivalent combinations should be able to take him out in a 2v1 almost immediately.
