Your Jirachi is completely overpowered at level 89 so yeah it can probably take the whole league by itself. In the case that this is in fact a typo then;
Defog is completely useless on Giratina. Replace it with Earth Power (Level 60)/Ancient Power
Azumarill is acceptable ingame though you might want to change Bubblebeam to something like Ice Punch
Feraligator.. please get rid of cut. Replace it with Crunch/Ice Fang
Azelf. I dunno but I'd suggest running a Nasty Plot set with Psychic, Shadow ball and another move
With Uxie I'd probably replace it with a fire type or something to deal with Aaron easily.
However Azumarill is completely underlevelled and all your Pokemon should be at last like mid 50s or something before taking on the Elite 4. If you do get them to that point then here's what happens at the elite 4: Aaron gets killed by fire types, but if you dont' have one fly jirachi will make do. Bertha is easy, you have Feraligator and Azumarill. Flint same thing. Lucian gets a little annoying, but Giratina can handle it and Jirachi can take out Gallade with a little luck and if you run the Azelf set I suggested, then Azelf has this in the bag.
Cynthia gets complicated. Having an Ice-type attack (Ice Fang/Ice Punch on Azu/Fera) will make this alot simpler since it destroys Togekiss, Garchomp and Roserade. The others, just hammer them dead with like Draco Meteor.
GL beating the Elite4, sorry about the big block of text and hope I helped!
