If I remember right and the Temple of Time is where you get Odin, then I think you might be on the lower end of "possible". You should try to level a little bit, and also what level are your job levels?

And how do you normally die? Does one of your characters get hit by all the enemies and then as you revive him you get taken apart, or do they keep attacking you and tear you apart within a couple turns? If it's the first option, smarter or more healing could be an easy fix, but if it's the second option you should probably level up.

Your party seems good, but if your dragoon or knight is a really low job level it might be better for you to use a different job for him. Job level, most of the time, makes more of a difference than job does, as long as they have nearly identical power in equipment.

And I'm not sure if you already finished this, but it was the top choice, so I decided to help
