I preface this by saying I have to admit ignorance to the Armored Titan's combat prowess and extent of its abilities.
Opponents:
Gomora: At a quick glance it should be apparent that Gomora is the best enemy combatant and should be the focus of the Mothra & Daughters Wrapping Company. Unlike Godzilla, he has no real way to escape once on the ground based on how his tail isn't prehensile; he has to put his whole body behind swings. Not likely that he'd have an opportunity to dig away, either.
Gorosaurus: It's a fairly reasonable assumption to make that Gorosaurus would attack King Kong based on their familiarity. Seeing how he fought King Kong in '67, with quick kicks and not a granddaddy kick like he utilized against a restrained, huge target like Ghidorah, I'm not sold that he could take down King Kong; especially one with more feats of durability than 1967 Kong, I'd argue. It should be a good, classic Kong vs. Therapod battle that ends with a broken jaw.
Zigra: From what I've seen, is largely useless on land. He just stood there and watched Gamera toss a rock at his face. Now replace that rock with a rolling ankylosaur
I don't see Zigra doing much outside of the water. He has potent beams, but for some reason didn't want to use them on Gamera. My knowledge on Zigra is fairly limited so feel free to send some material to back up some points I may have gotten wrong here.
Warbat: Could give some of my weaker members some trouble. I'm not sure if he displayed too much killing power. They seem to fight by constricting, which is its best bet. But with so many allies and the ability to communicate, the Warbat should be quickly beaten.
Armored Titan: No clue, but I don't think he has much in the way of ranged attacks to deal with Mothra which is a major point of contention.
The Good Guys
This is all assuming King Kong is wrapped up with Gorosaurus, alone.
Gabara isn't the best fighter by any stretch but his grappling electricity gives him a shot to counter the Warbat, without help. I am aware that the Warbat restrained Kong's arms, but that was after letting him grab itself by the face. That's why it's not a shoe-in Gabara victory. As with everyone, he should be able to handle Zigra. Gomora will give him trouble, but he can last for a little while before being forced to retreat/gets killed. No time limit for him, and no atomic breath for Gomora.
Goliath is vulnerable to the Warbat for as slow as he is, but his lightning shot can rip a flying Warbat to shreds. He's got Zigra in the bag. Gomora will also give him issue, and has a good shot at being able to break his horn. I seem to recall some tail-whips striking Ultraman's face. Goliath's firepower seems to be a cut about some of Ultraman's attacks but I still think Gomora can handle a lightning strike.
Anguirus Millennium is ever the wildcard. Just like last match, no one here really has a hope of stopping him - pending info on Armored Titan because he has actual arms lol. Gomora's tailwhips pale in comparison to Godzilla's, which Anguirus shrugged off. He can surely tank Gorosaurus' kicks as well. He's got the ability to strike down the Warbat.
Ebirah and Ganimes serve as distractions and can take abuse from the enemy for a little while, but they won't get a whole lot done on their own. Ebirah took atomic fire, so he's resilient.
Baragon's a tenacious fighter and should be able to give all non-arms having opponents issue. He's fast and aggressive. His beam could probably at least damage the Warbat, but won't do much against Gomora and Gorosaurus (who survived a gravity beam). He can tango with Gorosaurus for awhile, probably get the jump on Warbat with his leaping abilities (pretty nice counter there!) and get Zigra on the ground and tear him up.
I think the numbers allow my team to shine. It gives the Mothras ample time to remove a fearsome combatant (likely Gomora) and move onto another. Even if some matchups don't go our way, we have the numbers and durability to deal. But I'd like to know more about the Armored Titan, if anyone can point me to some videos.
