How long would it take to get a phD with each of these degrees?

A PhD is 8-12 years depending on many factors, only one of which is the field. None of those fields are worth getting a PhD in. In fact, most of them wouldn't even warrant a masters degree. The only reason to get a PhD in any of them would be if you wanted to teach at the college or university level - those jobs start out paying about 40k in those fields and it's hard to get them. A PhD will leave you vastly overqualified for all other jobs.
