English-speaking people usually greet each other in an informal way, so you can use these common conversational greetings for friends, family, as well as people you meet in casual settings.
1. Hey, Hey man, or Hi
You can use “hey” and “hi” to greet someone instead of “hello”. Both are particularly popular among younger people. While “hi” is appropriate to use in any casual situation, “hey” is for people who have already met.

2. How’s it going? or How are you doing?
If you’re trying to be particularly polite, stick with “how are you?”

3. What’s up?, What’s new?, or What’s going on?
These are some other informal ways of asking “how are you?” which are typically used to casually greet someone you have met before. Most people answer with “nothing” or “not much”.

4. How’s everything?, How are things?, or How’s life?
These are some other common ways of asking “how are you?”

5. How’s your day? or How’s your day going?
These questions mean “how are you?” not just right now, but how you’ve been all day. You would use these greetings later in the day and with someone you see regularly. For example, you might ask a co-worker one of these questions in the afternoon. Answer with “fine”, “good” or “alright”. By the way, notice that “good”, “fine” or “not bad” are perfect answers to almost any greeting question.

6. Good to see you or Nice to see you!
These casual greetings are used with friends, co-workers or family members that you haven’t seen in a while, so you might use this greeting along with a hug or handshake depending on your relationship with the person.

7. Long time no see or It’s been a while…
These casual greetings are used when you haven’t seen someone in a long time, particularly if you
meet that person unexpectedly.
