Is this expression usable? (telling how I've been doing in English.)

I bought a text book about English expressions a couple of months ago. (mostly American expressions)

It contains a lot of unfamiliar expressions. Most of them I've never heard of.

Please let me know whether it's a bunch of malarkey or not. (ex.) 

Here are some expressions.

Q: How are you? (I normally use this) = How's tricks? / How's it shakin'? / How's by you?

A: same as usual (I normally use this) = I am getting by / just muddling through / plugging along / Fair to middling.

A: not good (I normally use this) = Lousy / Crummy

A: keeping busy (I normally use this) = Swamped / I'm snowed under / Been running around like a chicken with its head cut off.

Thanks for those who answer in advance.
