Cedar can be weird like this, they may be grown together good enough to fall at once, or they could just split off on ya, won't know until you cut em.
If possible fall the 2 big stems together with the seam perpendicular to the hold wood, this will hopefully hold them together long enough to hit the ground... hopefully...
For the little guy, cut him free and drag him out with the skid steer before messing with the other two.
It might be a good Idea to have a couple of tree jacks on hand for this one
PS have fun limbing it...
