work out your sats of interest, those within 20 degrees of each other, and all receive either in ku - are best for offset dishes, and can combine three.
with the centre sat having the sides sats within 5-30 degrees.
that will make u pick all the three sats with one dish and three ku lnbs on an offset dish.
the same can be done for c band but needs a 9ft or so dish.
but the principle is working out your received sats, elevation and degrees from each other. then follows the practical.
example is eutelsat w4 and intelsat 802 - i receive both on 1 dish 90cm 2ku lnbs.
