You dad may have a long time left. HIV is no longer an immediate death sentence. Many medications can be used to control it and many people with HIV live longer than expected. That's not to say it isn't a serious disease because of course it is.

You can help by simply being who you always have been. Don't treat him like a fragile, breakable thing. He's the same person he was before. HIV doesn't change a person.

HIV won't necessarily develop into full AIDS for many years.
