Please check BS01 before asking things like this.
The short answer (I think) is that we don't know, since there hasn't been official work on their fate. Maybe someone's asked Greg but I don't know. I think the Mahri were rescued, I don't know how though. We don't seem to have word on Lewa. I think he'd be able to handle a few Agori though.
BS01 says: "After Teridax was defeated, they emerged from the Matoran Universe with the Skakdi and golden being. They traveled through Spherus Magna, eventually arriving on the shores of Aqua Magna, where the golden being created a fortress out of thin air on the nearby cliffs. Eventually, they were rescued." I don't know what source made this so, i would like to know myself.
About Lewa: "Lewa left the fortress while the others of the group debated on whether or not to free the captive Great Being, emerging onto the Great Jungle. He witnessed a massive bio-mechanical lizard kill a smaller reptile, and, spotting a few small villagers nearby, decided to warn them of the threat. He was unable to speak to or understand the language of the beings, but managed to understand that they were asking him where he came from. After pointing to the fortress he had emerged from, they were angered, and pointed their spears towards his throat. He was then dragged off by the Agori."
Yeah...Like I said I think he should be able to handle them. I wouldn't worry about him too much, he has very strong plot armour ><
