at least 40e-1a for each green and rune, maybe more
^ Ignore this. (originally written to reflect a "5a for all" comment, which I guess was edited prior to me finishing this post)
For the greens, these are among the more common ones out there, due to the ease and/or popularity of farming the respective bosses. 1-3a/ea is pretty fair, perhaps higher for Strongroot's, as that's maybe the rarest of this bunch, but depends on interest. That said, of the ones you listed, The Stonereaper is one of 2 greens known to have at least 3 different versions. If yours is the "3rd version," then it's quite a bit more rare, and you should seek an accordingly higher price for it.
In theory, Milthuran's could also have a 3rd version, but only the Stonereaper and Kepkhet's Refuge have been proven so far. Please contact me in game to verify which versions you have. I've sent you a message as well.
As for the rune, I will leave that to Oldschool Cool or perhaps others to comment on, as they are more informed than I am on those.
