Well, when introducing someone for the first time, it is not normal to relate all the details of your friendship and relationship to anyone within listening distance. This is considered to be, generally, 'unnecessary information,' and may indicate a lack of style, depending on the venue. "Here's my friend Mike," is quite adequate for almost any situation. If any of those present wish to ask for more details, then no doubt they would do so privately a little later.

If you want to say that he teaches English, and you don't have to pay, you could say something like, "He teaches me English for free."
So, in all, you could say something like, "This is my friend and Co-worker, Mike, and he teaches me English for free."

You can use these example sentences to introduce someone who you know in many dimensions.
Here are some examples:-

Paul " I'd like to introduce you to my friend William, I've known him for four years and he is my friend, co-worker and English teacher"
Wendy " It's my pleasure to meet you Paul."
2. He/she is my friend who also happens to be my co-worker and English teacher.
Paul "This is my friend Lisa, she is my friend, co-worker and English teacher. She wears many hats!"
Marsha "Oh this is a great person to meet!"
this is my friend who i work with, he also helps me with my English
this is my friend who helps me with my English, we also work together
saying "this is my friend who i work with, he also helps me with my English" or "this is my friend who helps me with my English, we also work together" are both formal ways to explain this to somebody. calling somebody a "friend that you work with" is more polite than just calling somebody a colleague because it means that you enjoy their company. rather than just being forced to see them because of work obligations.
He is my coworker, friend and also English teacher
Not only is he my friend but also my English teacher and colleague
These sentences explain that there is someone who is your friend, coworker / colleague (someone that you work with) and also their English teacher.
colleague is another term used for coworker.
when using "not only" this usually implies there is more than one subject within the sentence.
He/she is my colleague and friend that also helps me practice my English
When you want to explain to someone that the person you are introducing is a coworker, friend as well as someone that teaches you to speak English; then you may do so in the following ways:
-He/she is my colleague and friend that also helps me practice my English
