Kumusta ka na?

I have a really simple question...I am wondering what kind of ways you can say how you're feeling; other than mabuti naman or the regular stuff that makes you think the person only has a superficial knowledge of the language. For example, when I teach a class in English and I say "How are you?" and all the students answer back, "We are fine." or "I am fine" every time, I know their knowledge is only superficial. When someone at work says, "Hey Jennessa! How ya doin?" I don't just say, "I'm fine. How are you?" I say, "Oh I'm doing great! " or "Good", "Alright," "Not too great," "Awesome!", "Okay," etc...
How do you native speakers or advanced Tagalog students respond in Tagalog for some variaty?
