Question

sentence: I want to practice "daily life" English ?
Can I say so?

I want to learn more vocabularies related to daily life English but not too formal English.

Answer

"I want to practice daily life" isn't correct.

You could say;
I want to practice knitting. In my daily life I have a lot of free time.
What is your daily life like?
In your daily life, do you do much exercise?

Answer

I think 'Conversational English' is the term you are looking for - it is how you speak to friends and family in your daily life.

It is much more informal than standard 'text book' English.
