How rare is a double K class star system with 2 ELWs and 3 WWs (2 of them are terraformable)?

Let's see... Both ELWs are orbiting single K stars, that's common. Systems that have two ELWs are rare, somewhere around 3-5% if memory serves. So, it's a pretty good find.
Looks like you're really lucky. True, people tend to skip protostars, but even among Herbigs, ELWs are quite rare. Personally, I've been to over a thousand Herbig main star systems, and have yet to find one with an ELW.
Of course, in this latest system of yours, the heating from the B star certainly helps. Hm... Perhaps I'll revisit looking for Herbigs again.
Oh wow, I believe this is the fourth ever ELW to be found in the same system as an O-class star.
They are that rare.. and you are just fortunate
Perhaps we should switch roles - I hunt for ELW Herbigs and you hunt for ELW White Dwarfs
Hm, you know, on second thought, there's also that the ELW there is mostly heated by the second star (B, class O), it just happens to orbit the Herbig.
It's fun to see little surprises like this from the Forge even now, and to imagine what life would be like down on such a planet. Of course, there is the matter of the system being two million years old...

Hey, congrats! Since it orbits five stars, and the main star is a carbon star, it's already in GFL territory. I'm not sure how rare solo ELWs might be, since we can't tell them from the EDSM data dumps. Looking at the ELW list screenshots a while ago, they'd certainly be rare, but how rare exactly? I can't tell you, but your find is so rare already that for it, it doesn't even matter much.
I've actually been working on something recently that allows me to answer the solo ELW question*. I've used the ELW list from EDAstro, and checked which exist on EDSM (not all do - either EDAstro has other sources besides EDSM, or I've found culled systems already). I've excluded anything from EDSM that doesn't have a bodyCount set (this means it's too old to confirm whether the system is comlete or not). I've excluded anything not procedurally generated (basically, named systems).
After all that, there are 131019 systems in my data set. Of those, 197 consist of just 1 ELW and main stars giving a rate of ~0.15036% - putting them well in the Very Rare category.
There is also a single system in that set that, besides main star(s), has just 2 ELWs. At 1 in 131019, that's truly in the GFL category.
This is a fantastic example of one of the solo ELWs (not mine!)
* Assuming I've worked it out right!

Here are a couple of candidates for very rare (or maybe just rare, I'm not too sure). Whatever the exact rareity, I figured both systems were unlikely to exist and worth sharing.
First up, and probably the rarer of the two, is Dryoea Flyi FG-Y f1107. This system contains an ELW which is a moon of a T-Class Brown Dwarf, which orbits the barycentre of a Blackhole (Primary star) and a Neutron Star (Secondary star).
The second is Dryoea Flyi IM-W f1-3475 and is perhaps a little less clear in terms of how rare it is. The primary star is a black hole, however the ELW orbits the barycentre between the blackhole, a Class DCV White Dwarf and a K class star at a distance of only 676ls. Theres also a G class star in the system. Now, I suppose the fact that there's G and K Class stars in the system increase the chances of an ELW existing, however the fact that a black hole is the primary star, alongside that it orbits so close to the barycentre between that black hole, a white dwarf and the K class star would make it pretty rare right?

By the way, if anyone here wants a numerical score for their ELW(s), the ELW list has been doing that based on the EDSM data since a month ago.
@jacob99 : in your second case, the applicable ones would a black hole system main star ("very rare" category) and ELW co-orbiting three stars ("rare" category). So yep, it's pretty rare alright.

What would this count as? Main star is a WD with a binary L star. Around them a M star that has an elw.
WD primary is in the GFL category. Nice find!
Thank you. I'm just curious why it's the main star that's relevant and not the star that the elw is orbiting.
Because the main star is the most important star in the system. In your system's case, sure, there'd be a decent amount of ELWs orbiting M stars, but there are very few ELWs (orbiting anything) in white dwarf main star systems.
