Kenma and Lev are seen to be working together to perfect the timing of Lev's whip spike attack. It is mentioned by Kenma that Lev's technique is almost nonexistent and that his attacks are sloppier than Hinata's.

At first, it seems as though Kenma dislikes Lev, but this feeling eventually disappears as the two are able to attack properly later in the series. Though, Kenma still roast him him from time to time.

As for Kenma and Inuoka, not much was really shown but I presume Kenma also gives him the same approach he gives Lev but less harsher. One time where they were strategizing for their match vs Karasuno, Kenma called them "musclehead squallings" for not thinking before speaking.

Not much was also shown between Kenma and Shibayama. No surprise there since Shibayama is a minor character. He is shy and gentle yet determined. It was clearly shown that he respects Yaku as a libero and as a senior. And I think that also goes with his other seniors like Kenma.

Remember during the match against Nohebi, when Yaku was injured and he was called in as a substitute, Kenma suggests that Shibayama only rotates with Lev. Some may see it as Kenma not acknowledging his capababilities as he is far less skilled as a libero.
