You can say things like {Beware} {Enemy} {Area of effect}, I do not know of any specific translation for "debuf". though you could maybe mangle it with "trait".. or use existing spells as a way to explain. Also for position there is a position section, it has things like {rear}, {side}, {outside}, {this way}.. You should check it out. I have two characters on (different) JP servers, and I am trying to solve this problem too. DF queues are far worse there for many dungeons depending on time of day (as a WHM it took me 90 minutes to queue for Toto-Rak yesterday) and as a result many JP will queue up, some of whom have only limited english speaking skills.

I would basically read through all of the auto-translate menu and look for terms.
