You use "knows" if the subject is one person, other than yourself or the person or people you're speaking to. For example, he knows, she knows, or it knows. Otherwise, you generally use "know"; for example, I know, you know, we know, they know. Also, if you have a helper verb such as "do" or "does," then you always use "know"; for example, "Do you know the answer?" or "Does she know him?"
To me if you know how the use the words properly then use them.
"Knew" is the past tense of "know." In the present tense, you would use "know" instead. For example: "I know the answer."
You should use no when disagreeing. Example: No, I do not want to proceed in walking. \ You should use know when saying someone knows something as in they know maths, english, ect.
