What would Jenner think of Nayiri and Fel? Nayiri is a smol, hedonistic Sith marauder with cybernetic implants and a penchant for taking the most direct path to her goal as possible, but she would honestly rather be adored than feared and does try to cultivate a "savior of the fighting ranks" reputation. Fel is a pink lethan Twi'lek whose life work as a Jedi is cleansing Sith artifacts of dark side "auras." She's more of an indoors Jedi and while she supports the war, she doesn't usually fight.
Jenner could either get along with Nayiri or be uncomfortable with her depending on circumstances. She gives preference to any Sith that’s not an outright bully and is more likely to respect them. OTOH, she doesn’t trust any Sith and thus keeps her distance, especially from people more heavily involved in the war than her. And she finds sexual forwardness intimidating. So she’d probably like Nayiri alright but steer clear of her when not pressured to associate with her.
As for Fel, Jenner would have little to do with her as a Jedi. She’d be put off by the idea of ‘cleansing’ Sith artifacts, and she’s not a fan of Jedi or the war. But any Jedi that’s not too involved is a Jedi she’s much less likely to kill, and even if she ran into Fel in that context she’d try and leave her alone as long as she wasn’t in the way (or a designated target.)
