Is this sentence correct?

"He has chat to Ben and said that he will be in office in a few minutes. And also he asked from him whether everything is ready to make the next release and I told him that everything is ready and can release."

Furthermore, please suggest me a resource that I can use to learn tenses in English.

Thanks
