Need advice on W-8 form

I was asked to provide appropriate W-8 form.
For Non-US persons and entities: A signed W-8 form (W-8BEN, W-8CE, W-8ECI, W-8EXP, or W-8IMY).
So, there are 5 different W-8 forms (W-8BEN, W-8CE, W-8ECI, W-8EXP, and W-8IMY). I would really appreciate if anyone advices what W-8 form I should use.
I am Non-US citizen/resident and I am a private person (not company).
Thanks
