Assuming the masses of the 8 outer stars are quite small compared to the two large ones, they'll probably all be expelled from the system. The binary stars will stay together as long as the ejected mass from the exploding star is less than half of the combined, pre-supernova masses of the two stars.
Mostly correct, I'm not going to comment on the whole thread, because I think some of that Math is correct, most of the answers are already here...
What I do have to say, is that the present stars, and other celestial bodies (I still refuse to believe they're all stars, it's a well known fact that Jupiter actually EMITS energy, so it is possible that those 8 other bodies are super-gas giants, Of course this is unpopular scientific conjecture, so don't pay much attention to it

) a very large quantity of the mass, and energy sprayed out from the supernova, would be absorbed by these bodies, considering the enormous gravitational forces that are balanced in that system, it's also likely the explosion would result in more 'streamers' like a Gyser (that doesn't go off regularly....just the once) being aimed in multiple directions because the rock is in the way in the other directions, primitive example I know, but if the star that went supernova (...hell it wouldn't even be super nova, it would just be nova and form a planetary nebula, unless the SJ's actually gave it more energy then was available, planetary stars, like our own, do not get large enough to create super nova's, even when they are towards the end of their cycles and the elements they contain are EXTREMELY Heavy...) in the centre of the system and the other bodies were spaced equi-distantly around it, then it would most likely be that about 60-70% of the energy from the nova wouldn't even escape the system, and that's not even accounting for the amount that's absorbed by the Oort Cloud, so we'll call it 70% including the Oort, take another 5 off for the distance between the systems and the possible dark matter encountered between them, THEN take off another 10% for the next Oort cloud, which would leave you with about 15% of the original blast, at least 10% of this would be easily handlable by the atmosphere of a planet like Earth, so long as it's not sufficiently thinner, there would only be 5% left to do damage, now the unfortunate thing about all this conjecture, is I really can't garantee the numbers AND beyond that, can't tell you how much it will affect our ecosystems.
What I can tell you, is the remaining energy, will primarily be Gamma, probably talking about 60% of it, then about 20-30 would be xray, the rest would be heat/light..
Of course I'm guessing, but it doesn't need to be taken as gospal
