The thing is, as strong as Crom is, there's no way he can beat Issei in 8 minutes. Issei would surely last long enough until Ddraig is emerged and at that point Issei's team would have the power advantage. Issei could go somewhere else or he could send Ddraig to go after Rias.

You are right in Balor Rias beating Grayfia but it also depends on Grayfia's state of mind. If she's not hindered by her emtions than that would be problematic for Rias. Not powerwise but stamina wise because even if Rias beats Grayfia, Rias would not be in the best shape due to her Balor form stamina consumption. Especially if the fight last for some time. At that point, Rias would be even worst shape than Issei.

Kiba vs Asia is tricky. The thing is Kiba has nothing that get pass Asia's defenses. We're talking about someone that can block attacks from gods. Rizevim, Artemis and even Crom. None of them could penetrate Asia's defenses and if Fafnir sees Asia in danger than that could trigger his rage mode to which Kiba would be in serious trouble.
