How can I find and apply heading 3, 4, 5... in word file?

I saw heading 1 and 2 in Quick Style, but couldn't do 3, 4, 5... in any way,
I looked into Help, opened "apply styles" window, there are even fewer styles
in there, I tried to create one, but was told "heading 3" is already exist.
Please help! Thank you.
