こう: like this, it's a kosoado word just like どう and そう
滑れる (ずれる): to slip, but the kanji is used incorrectly (the word takes no kanji, the entry for ずれる in EDICT is incorrect. 滑れる is actually read すべれる=to be able to slip)
あひら: not a word, you or your list has a typo. maybe あひる(=duck)
~帳 (~ちょう): (bound) papers/notes
ex: 電話帳 = phonebook
ex: 単語帳 = flashcards
ex: 手帳 = (pocket) notebook
Keep in mind that every JLPT vocab list is a heap of unproofread crap with automatically generated EDICT definitions. They only differ in their level of crappiness. I found the (pro) playsay list to be the best, but it was still full of mistakes.
