- Elfilin
GK: We know he upscales from Magolor even in base form but we don't know by how much and how powerful his forms are. Team Kirby is said to be stronger as his profile says, but it's a 4v1 with opt items, they would most likely only be stronger as a team.
Void: The VT in the main story upscales from any 1 Star Ally, like Magolor, fighting evenly a 4v1 battle. Void is far stronger, but we don't know by how much.
Chaos Elfilis: Kirby & Magolor grew stronger than in Star Allies in Fighters 2. Chaos Elfilis is the canon final boss of a game after that. He got defeated, yes, but can be due to skill in a way that makes them more powerful than Kirby. Void is a non-canon fight, so fighting him and the second VT doesn't make the Star Allies any stronger than when they fought the VT of the main story, it just means the characters can get that powerful.
Kirby: Similar to what was said before; Is he as powerful as Chaos Elfilis? Maybe, at least he's close enough to defeat them. Is he as powerful as Void? Who knows, maybe he because as powerful already, or maybe Void is super broken next to the first VT and Kirby isn't close. Or maybe he is more powerful due to growing in power as the games went on. Same with Galacta Knight.
Elfinin: We know he is either somewhat close to Kirby or as powerful as him due to his display at the end of the main story in Forgotten Land. At the end he and a reborn Chaos Elfilis "became one" again, but what does that mean? Did Elfinin add Chaos Elfilis' power to his own? That would be similar to what Fecto Forgo did with Elfilin, growing better. But then it could be an identity and/or purpose thing that has nothing to do with power at all.
