These new #1s are continuations of their respective protagonist's narratives, continuing their stories from before their titles were relaunched.

You can read any of these new books without problem, they are meant to be new reader-friendly. So, if you want to begin reading Daredevil, you can start with Daredevil Vol 5, and you don't have to read the previous four volumes (unless, of course, you want to read more material about the character).

In the case of this current relaunch, it began in October 2015. This is beacause last year's mega-event called Secret Wars was meant to end in October. So, all of the titles were ended before Secret Wars began (May 2015), and they were then relaunched in October.

So far, Secret Wars is the second recent event that caused a line-wide relaunch. With the other one being 2012's Avengers vs. X-Men. However, there have been other instances where titles were relaunched for no reason (like Daredevil Vol 4 and Captain Marvel #8). Unless constant relaunching becomes a habit (which I personally hope doesn't happen), there's no really a given pattern to when they decide to start a new volume of one or all of their series.
