"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?

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.
