It is actually much easier for me to reply your questions in English. I often deliberately do it in Chinese, so that more people can understand better and can learn from how I correct those mistakes I have noticed.

(F) In Chinese we say we forgive the mistakes of others, but in English we do not say that; we only forgive a person for his mistakes. So the proper way to put it is:
Forgives you for your mistakes.

(L) It should be Loves you for what you are. "What" refers to what kind of person you are, i.e. your personality, your character, etc., whereas "who" refers to what your name is. In Chinese there is not much difference, but in English there is.

(O) It should be "Offers support"
