①ＳＩＮＧＵＬＡＲ I ⇒　私(men & women) 、僕（men ) You ⇒　あなた、きみ (あなたis more common but we usually call people by family name with ～さん） He/She ⇒　かれ／かのじょ　　　　　　　 ②ＰＬＵＲＡＬ わたし ⇒　わたしたち あなた　⇒　あなたたち かれ／かのじょ　⇒　かれら／かのじょたち　　 　　 Basically, we use these words. But usually we call someone by his/her family name or nickname up to the relationship in between. Am I answering your question?

〔二人称・単数〕Second-person-singular ＊人を呼ぶときは、苗字で呼ぶのが一般的。When you call a person, generally called in last name. 「○○（苗字）さん」 ＊親しくなったら、名前やあだなで呼ぶこともできる。Became friends, you can also call a name or nickname. 「○○（名前）さん」、「○○（名前）ちゃん」、「○○（名前）くん」、「○○（名前）」、「○○（あだな）」 “ちゃん”は、女性の友達や若い女性、小さな女の子や男の子に使う。"chan" is for women friends and young woman, and a little girl or a little boy. “くん”は、自分と同等または目下の男性に使うが、男性が目下の女性を呼ぶときに苗字+くんを使うこともある。The use of "kun" is for your equivalent or inferior men, sometimes be used kun + surname when men call subordinates women.小さい男の子にも使う。and for little boy. あなた・・・同等またはそれ以下の人にしか使えない。会話のときはあまり使わない方がいい。you can use it only for people of equal or less than you so I can not suggest that you use in conversation. 最近は減ったが、昔は妻が夫に対して使った。Although the recent decline, the old days the wives used for her husband. 君（きみ）・・・男性が同等またはそれ以下の人に対して使う。used only for people of equal or less than you usually by men. 奥（おく）さん・・・名前を知らないが、既婚であろう人を呼ぶときwhen you want to call the unknown woman would be married. お嬢（じょう）さん・・・名前を知らないが、未婚であろう人を呼ぶときwhen you want to call the unknown woman would be unmarried. お嬢（じょう）ちゃん・・・名前を知らないが、小さな女の子を呼ぶときWhen you call the unknown little girl ぼく・・・名前を知らないが、小さな男の子を呼ぶときWhen you call the unknown little boy お客様（きゃくさま）・・・客を呼ぶときWhen you call the customer 「○○（苗字）様（さま）」・・・名前を知っている客を呼ぶときwhen you know the name of customer. ＊注意！Attention!　自分より目上の人に、「あなた」「君」「ちゃん」「くん」を使ってはならない。To superiors than you, do not use the "anata" "kimi""-kun" "-chan". Do you want to know more？ also about the third person and plural? Sorry my english, it is so bad, huh.

Some people say "Atakushi". あたし・・・女の子が親しい人と話すときに使う。girls use when talking with friends. うち・・・関西の方言だが、最近は別の場所でも若い女の子が使う。Kansai dialect, but recently young girls also used in another place. 僕（ぼく）・・・男性が子供から大人まで使う。私には若々しく少し上品に聞こえる。Used by men from children to adults. It has sounds youthful and a little tasteful for me. 俺（おれ）・・・男性が使う。子供はあまり使わない。少し力強い印象を持つ。Used by men. By the little boys, it is not used very often.
