1) When we greet or farewell someone in Chinese, normally we will put the person's name before the word "Nǐ hǎo你好" or "zàijiàn 再见". For example, "Hello, Sally!" will be "Shālì nǐ hǎo. 莎莉你好.". And "Bye, Peter." will be " Pítè zàijiàn. 皮特再见。"
When we greet someone with their title instead of their name, for example, we greet the teacher as "Ms. Kelly" or simply "Ms." , we will abbreviate "Nǐ hǎo你好" to " hǎo 好". So the greetings to her will be "Kǎilì lǎoshī hǎo! 凯丽老师好!" or simply "lǎoshī hǎo! 老师好!"
2) 们(men) is a plural suffix for person. For example, when we talk about the class, which is made of "classmates", you will say "同学们 tóngxuémen” . 们(men) is also a personal pronoun, which makes words like "we" "they" etc. (We will learn those in future.) Remember, unlike English, we don't put 们(men) every time we talk about plural. So far, you just need to learn that we say "同学们 Tóngxuémen” when we talk about the class.
3) "Time + 见 (jiàn)" = See you +time. For example, 明天见 (míngtiān jiàn)=see you tomorrow. The same pattern will be used on sentences like "See you this afternoon 下午见(Xiàwǔ) !", "See you this weekend! 周末见!(Zhōumò) " etc.
