(1) I a little know.
(2) I know a little.
(3) I know a little bit
(4) I a little bit know.
(5) I'm a little tired.
(6) I'm tired a little.
(7) I'm tired a little bit.
(8) I'm a little bit tired.
I'm confused.

I don't think every sentences are correct.
Would someone please explain about "little"?
Sure. I know english very well, and have a very high grade in english at school. I am learning japanese myself. The word little can be confusing in english. Like kanji, you can use little different ways. The sentence structure is different in english; it's not like japanese. In japanese I think little is "chotto".
(1) I a little know. <--- This one is not correct. It should be: "I know a little."
(2) I know a little. <--- Correct
(3) I know a little bit <--- Same as "I know a little.". It means the same thing.
(4) I a little bit know. <--- Not correct.
(5) I'm a little tired. <--- I'm is just a more easy way of saying, "I am.". This is correct. This sentence means you aren't tired much.
(6) I'm tired a little. <--- Not correct.
(7) I'm tired a little bit. <--- It just means the same as "I'm a little tired."
(8) I'm a little bit tired. <--- Not correct.
If you need anymore help, please let me know. I'd love to help you out.
Good luck!
(8) I'm a little bit tired. <--- It means the same thing as (7). In english, you can switch things around and it still means the same thing. I know it can be confusing, but keep at it. And most importantly, ask questions! The more you ask the more you learn!
Please disregard the first reply to (8). I'm tired and can't seem to find a way to edit it. Anyway, read what I said the second time about (8).
Oh, and in your signature it says to please correct you in any errors you make. Here's an mistake you made

This is what you said)
"I don't think every sentences are correct."
This should say: "I don't every sentence is correct." I can't really explain this one, it's just how english works.
