I have a quiet gorgeous friend; her name is Putri.
This is good. I see that Azeri noticed a run-on sentence. If you give one sentence, and it is complete, you need to stop before you write the next one. You have three choices:
I have a quiet, gorgeous friend. Her name is Putri.-------- I used a period to end the sentence and start a new one.
I have a quiet, gorgeous friend; her name is Putri.---The semi-colon acts like a period.
I have a quiet, gorgeous friend, and her name is Putri. ----- You can also make a compound sentence by using a comma and the word "and" (a part of speech that is called a conjunction)
Any of these (above) would be okay.

No s if you write about "I" or "you" or "we" or "they"
I want
They want
You want
We want
But use s if it is like this:
He wants
She wants
Putri wants
