Thanks!
Let me put the lists together. I've highlighted the parts of the English names that my friends use in Japanese. The names that ShadowCadja gives are references to their jobs and work just as well. ^^

Ruffletuft Kupta Kapa - カパ − 斧 ("ono" is axe)
Whiskerwall Kupdi Koop - クープ − 剣 ("ken" is sword)
Furryfoot Kupli Kipp - キップ − 白 ("shiro" is white (mage))
Woolywort Jolly Kogi - コギ − 弓 ("yumi" is bow)
Pukla Puki Pomburner - プキ − 黒 ("kuro" is black (mage))
Puksi Piko Shaggysong - ピコ − 詩 ("shi" is bard)
Pukna Pako Tailturner - パコ − シ ("shi" is short for シーフ ... "shi-fu" is the katakana spelling of thief)
Good King Moggle Mog XII - 王 ("ou" is King ... but sometimes referred to as ボス or "bosu" (boss))
