From what I know, there is the Belin empire with Russian(ZA-08 Zarov), German(ZA-11 Zyclon) and Japanese mechs(upcoming Samurai). The Zabul(ZA-04)(pic related) is the predecessor of the Zarov.

The Califia Federation uses the OCR-22 Yunque(fight type like Dragonar, Windam, Flag) and OCR-24 Acteon, an upcoming knight like MS that resembles the Tallgeese and Gyan.

The Trade Federation also has another MS branch that is low cost with the Buck and Buck II. Buck resembles Gundam AGE grunts like that Zila and Genoace/Adele. Buck is a first generation MS that has also been sold to third parties(Like the Hellion from Gundam 00), not sure if it has been retired from the regular army. The Buck II looks like Nadescio's Aestivalis with more curves.

There is also another Federation that uses Gundam AGE looking grunts. It might be an African Federation.
