How do you say daily phrases in Japanese?

How do you say these phrases in Japanese?

• I'm trying to learn Japanese and I don't think websites and translators (especially these) are NOT helping much. I want to learn phrases I use in my daily life or might come across to once in awhile. Please tell me how to say these phrases in Japanese: Whatcha doin? (I could never find a phrase like this anywhere, may be it's not Japanese norm to ask this kind of question) What do you have there? I can help you. Can you be a little more specific? What's the matter? (towards someone who's depressed/crying) Do you need something? May I be of assistance? Yeah that's all.

• Answer:

  「どうしたの？」　- What's up? ("Doushita no?") 「これは何ですか？」 - What's that? ("Kore wa nani desu ka?") 「私はあなたを助けるできる。」　- I can help you. ("Watashi wa anata wo tasukeru dekimasu") 「あなたはちょっとすこしもっと詳しいできますか？」 - Can you be a little bit more specific? ("Anata wa chotto sukoshi motto kuwashii dekimasu ka?") 「大丈夫（ですか）？」 - Are you okay? ("Daijoubu [desu ka]?") 「あなたは何か必要ですか？」 - What do you need? ("Anata wa nani ga hitsuyou desu ka?") 「私が助けとなることもありますか？」　- May I be helpful? ("Watashi ga tasuke to naru koto mo arimasu ka?") I hoped this helped!! ^.^
