    The will be a G2v star with the sam mass, radius and luminousity of our sun

    Planet 1: 0.5 earth masses orbiting at 0.51 au
    Planet 2: 1 earth masses orbiting at 0.63 au
    planet 3: 2 earth masses orbiting at 0.78 au
    planet 4: 0.2 earth masses orbiting at 0.85 au
    planet 5: 4 earth masses orbiting at 0.95 au
    planet 6: 0.3 jupiter masses orbiting at 4.2 au
    planet 7: 0.08 jupiter masses orbiting at 6.5

    I believe you need to know the orbital eccentricities to reasonably assess orbital stability. At a glance, it appears the first 5 planets are just too close together to retain long term stable orbits. Planet 4 is particularly suspect due to its relatively massive and nearby neighbors. N-body calculations are not simple.
