This is not an easy question. It's hard to gauge their strength, because there are not many fights with them and well established characters.
Kinemon is the only one who did some fighting outside Wano and Zou. He fought with Brook and he killed a dragon with Zoro. Strength wise, he could be consider to be above mid trio, but maybe a bit below monster trio.
Kanjuro was hiding his true strength and Raizo did nothing outside Zou.
Neko and Inu were seen fighting against Jack, so did Ashura Doji. They might be consider to be on equal standing.
Denjiro idat least aa strong as they or maybe even stronger.
Kiku and Kawamatsu are as strong as Kinemon.
Izo was WB division commander. Overall they should be on the level of Calamities /Sweet Commanders.
Overall, they are most likely stronger than Straw Hat's as a crew.
