Presumably you're talking about Blaster, Brawler, Swindler, and Vortexer. The names are exactly the same in the JP version, in the same order, written in katakana.

1- ブラスター (bu-ra-su-taa = blaster)
2- ブロウラー (bu-ro-u-raa = brawler)
3- スウィンドラー (su-wi-n-do-raa = swindler)
4- ボルテッカー (bo-ru-tek-kaa = vortexer)

Whether the naming makes sense to the actual mobs is another story, but they at least match up between Japanese and English.
