How many of those stars have habitable exoplanets (assuming there is such a thing, which I doubt)?

This takes a couple of definitions of "habitable". Proxima Centauri B for instance lies in the habitable zone in times of normal brightness, but would be over-exposed to radiation during periods of signiicantly increased activity. However, presumably being tidally locked, the backside or the twilight zone of the planet might offer the temperature range we would deem habitable even in times of greater activity.

If you mean habitable as in having a biosphere supporting an oxygen atmosphere, probably none. Having conditions where such a biosphere could be introduced, possibly a few.

Allowing domed habitats without intensive thermal requirement - probably quite a few.

Having a planetary magnet field to ward off cosmic radiation - hardly any.

All of these at once? Probably similar to a jackpot in a lottery.

So... you're saying there's a chance?  :)

and the TRI Tac game FTL 2448 has great list of real world close systems

I'd use Wikipedia for my research these days.

Unless TriTac has revised that list of systems, new instruments have rendered that list entirely obsolete!
