My opinion is: I understand you dilemma 100%. This is a classic junk debt. Garnishment laws vary by state and I am not sure about KY, but I do know that most states only allow one garnishment at a time. If other garnishments are ordered; they must wait in line. Since I cant give you a definitive answer regarding the number of simotaneous judgments, you may want to contact an attorney. Try

Now that a judgment was issued and appeal or reversal would be difficult and costly. Also, attending the garnishment hearings would be wise because they determine the amount of the deductions.
