How is my grammar in the written English?

I take coffee every morning - Present Simple.
Gramatically correct, however nobody says "I take" coffee. Coffee is a drink, people say "I drink coffee."

I`ve to attend drawing class in every friday - Present Perfect
Gramatically incorrect, and nobody speaks like that. Friday should be capitalized. People say "I have class ON Friday." not IN friday.

She has working as the teacher for 10 years now. - Present Continues
Correct: "She has BEEN working as A teacher for 10 years now."
In this case has cannot stand on it's own.

She has been watching Korean movies since 1998. - Present Perfect Continues.

FUTURE TENSES::

I will go for grocery shopping tomorrow - Future Simple.
You don't need the word "FOR". Think of it like this
I will go shopping tomorrow.
I will go grocery shopping tomorrow.
GROCERY is just modifying the word shopping, telling you what type of shopping it is.

good
I will be watching movies tomorrow - Future Progressive.
good
I will be taking yoga classes from tomorrow - Future Perfect Continues.

If you only got one gift, then THE is correct. If it was one of many, then use the word A.
