What is the smallest a star could be and still support livable planets/planetoids?

Also, what size star is needed to spport three livable planets?





To explain, I am trying to model a binary star system where one star is larger and supports three livable planets (consecutively) and a smaller star can support livable orbiting bodies. I'm trying to figure out the conditions of a system that would allow for that.|||It would be hard for one star to support three livable planets, because a primary factor in whether life is possible on a planet is its distance from the star that it orbits around. It has to be within a certain range of distances. If there were three planets orbiting around the same star, it would hard for all three of them to be orbiting in the same range.
