What are the most common Chinese honorifics? What are the most common Chinese honorifics? As far as I know we have:

大人 = respect, like the -sama in Japanese
贵 = your
臣 = your servant
朕 = I (only used by the emperor)
When addressing the listener's family, a prefix 令 (ling4, which has a meaning of good, lucky) can be used:

令尊, your father
令堂, your mother
令郎, your son
令嫒, your daughter
令兄, your elder brother
令弟, your younger brother
令姊, your elder sister
令妹, your younger sister

Correspondingly, when addressing the speaker's own family, a prefix 家(jia1, which means home, family) is used:

家父, 家严, my father
家母, 家慈, my mother
家兄, my elder brother
家弟, 舍弟, my younger brother
家姊, my elder sister
家妹, 舍妹, my younger sister

舍 (she4, my humble house) is used only with the younger of the same generation, or the younger generation:

舍侄 (brother's son), 舍甥 (sister's son), my nephew

My son and my daughter are 犬子, 犬女. 犬 here is puppy. But it's extremely rude to call others with any dog related words.
In daily informal cases, we can use:

您 as a replacement of 令
我 as a replacement of 家、舍,
common words like 父亲, 母亲, 哥哥, 弟弟, 姐姐, 妹妹, 儿子, 女儿

Examples:

您父亲, your father
我弟弟, my younger brother

My father and my mother can be 我爸爸, 我妈妈. But 您爸爸X or 您妈妈X is not proper because 爸爸 and 妈妈 are not honorific while 父亲 and 母亲 are.
Besides, 尊 (zun1, honor, respect) is a honorific prefix:

尊夫, your husband
尊夫人, your wife, also 嫂夫人
尊驾, you
尊师, your teacher
尊长, your elders
