Well with the first part of this post, as of now he's engaged to 7 and i'm sure many more are on their way after the vision that was giving to Issei. But with the children stuff i think that will be retcon. Mainly because that part was giving when the author only still had in mind 12 waifus. But obviously he changed that idea by having the list increased to 15 with the latest volume. You can tell it was originally only 12 because of the 12 heavenly breast thing, meaning 12 waifus. But since some harems over the years have been increasing in waifu numbers. Even two where the mc had 9.Might be more that have close to that number, just haven't read or seen them yet. I think the author wants to put it at a level that others won't reach. As for the first waifus thing, i have a feeling they all get married around the same time. Which will be tough since each one wants a special wedding in a different spot. lol That's why i say around the same time. My guess it will go in order of engagements. Last but not least i'm sure some of the children names in such won't change later down the road. But the raw numbers of children will increase. Even if we go the conservative route, i would say each future waifu having 2 kids each. Which it's possible it could go to a higher average then that depending on what the author does. Even with the conservative number that's 30 kids and that could increase if the vision he got was 15 plus, since i believe it was stated others weren't seen could just mean future waifus that haven't been met yet. But that's just what i figure from the info that has been provided so far. We'll know more i'm sure in future volumes. Maybe even get more info in next volume or two. But definitely be interesting seeing how things pan out in the long run. :3
