Should I say "I am the owner of ABC company" or I should say "I am the owner for ABC company"?
This is a clear-cut situation fortunately. Using of is definitely correct here, whereas for is not correct.
Of takes the role of the possessive preposition here. This is evidently appropriate, since the person possesses the company in some respect here.
I would go with:
(a bit like: "I own abc company")
"owner" and "for" are not particularly linked together, "for" being here to introduce a purpose or function (and that wouldn't fit your example).
