1) My father is not at home. He is at work .He will be back after nine o'clock.

2) My father is not here at home. I think he is at his work. He said that he will be back by 9 p.m. <means before 9 o'clock>

Ex: He said he will be back after 9 p.m. <different meaning than 2)

3) My father's at work and he will come home after 9 o'clock. <spoken form father's = father is >

4) My father went for a job just a few minutes ago and he said he wil be back after a few hours.
