in human terms. how long will it take to charge a phone, and how many times can it be used to charge my phone (total mA hours)

Assuming the upper end for the calculations,

About 37,000 hours

5Ah * 3.7V= 18 Wh

18 Wh/ .0005 W= 37kh

Or about 4.22 years

and it "lasts" over 20 charges (5years per charge) if it lasts 100 years (though it likely doesn't last 100 years, but has a 100 year half life)
