I and my friend go there together.

Answer:

Your English is wrong in some sentences:
You wrote: "it is malaysian pen." The article is missing. The sentence should go: "It is a Malaysian pen."
There is another mistake: You wrote: "I and my friend go there together." Instead of I you should use me. "Me and my friend go there together."
Make sure to start a sentence with a capital letter.

This is my pen.
My pen is silver and blue in colour.
It is a Malaysian pen.
This pen costs 9 Dollars. (Plural S after Dollar!)
I bought it last week.
I bought it at section 2.
Me and my friend went there together. (Past tense is better here).
I really love this pen.
