日本語実践！My first Japanese vocabulary practice

My first piece of vocabulary and grammar practice. I've learned the は、の、か、が & も particles and attempt them all here. I have also learned several kanji and intend to look up more as I study more Japanese grammar. Any corrections, or tips for studying would be most welcome! ありがとうございます！

私の名前はルーイーです/ My name is Louis (polite)
こんにちは、あなたの名前は何ですか？ / Good day, whst is your name? (polite)
あなたの猫の名前は何ですか？ / What is your cat’s name?
私はとても元気です / I am very well (polite)
私は元気じゃない / I am not well.
私の猫の名前はオジー / My cat’s name is Ozzy.
オジーは猫 / Ozzy is a cat.
私は猫じゃない！ / I am not a cat!
オジーは猫でも私は猫じゃない！/ Ozzy is a cat but I am not a cat
誰が猫？ / Who is the cat?
オジーが猫 / Ozzy is the cat.
私は二十四, 私もは男性 / I am 24 and I am also male. In this case, 私も男性です is ”I am male too” usage of "also" in japanese is different in English.(sorry my english is no good)  
私は女性じゃない / I am not female.
今日は9月18日 / Today is the 18th of September
