Verdict:
Megalon and Mechagodzilla are decent support due to the former's endurance and weapons and the latter's firepower and reactionary battle strategy pushing Gamera and Kong back. King Ghidorah's beams and strength pretty much make him the muscle of his team, wrestling Godzilla back. Orga's strong energy attacks will do some heavy damage. Monster X is the real threat between them all, strong short range and long range alongside Orga as well as the Keizer form that'll keep them stuck in attacks while throwing them into each other.
While it will hurt Megalon and Mechagodzilla can put the hurt on Kong and Gamera, Heisei and Orb are likely going to be too much for them. Even with the other two, they'll still need to work to beat them which isn't good for them in the long run. Godzilla already defeated him, an having backup will be help. His agility will really be tested in the need to he careful, but Kong can charge the axe which will really help as the close range issue Is helpful against their enemies. Orga and Monster X will be the issues here amongst the Dark Mysterious Star Alliance members.
Orga's long range was already mentioned but the regeneration will make him a wall to pick at even with the stronger attacks given how well he handled 2000's atomic ray. However, destroy the UFO and Orga becomes too slow to continue on to victory. Godzilla Heisei would be able to defeat Keizer Ghidorah though it would be a hard fought battle. Strong attacks especially with Spiral Fire Rays as well as a way to break free of the gravity beams with the nuclear pulse gives him a chance to win. Godzilla's team can win despite going through a war against these adversaries...
