Major Miram Ecter is a human mechanic in service to the Republic. Older woman who can see Ax has had more than a few upgrades over stock models, and has survived more combat than she can find evidence for in his hard drive. She appreciates a droid that's proven itself (even if it can't remember doing so), and consider Ax a bit more reliable than the usual bulk-purchase astromechs she gets in her shop. Might be more willing to assist with his upgrades in the future than your average mechanic, and is a long-time military member so knows people who know people, and has some rank she can pull on certain things if the situation calls for it.

7-3PX is a surprisingly-scrupulous spy droid. At some point during Ax's tenure at the Hutt's garage, 7-3 was spying on the Hutt's assets for Corellian Vehicle Reclamation (a more legitimate Repossession company than the Hutt's more illicit counterpart). 7-3 posed as one of the Hutt's protocol droids in need of some touch-ups as well as a couple upgrades. Ax was quick, efficient, and didn't ask any difficult questions about why a protocol droid was armed. 7-3PX keeps a mental list of trustworthy mechanics to seek out should he find himself in need of maintenance, emergency repair, or upgrades, and Ax is on the list. 7-3 is already aware that Ax no longer works at the chop-shop, and surmises he now works for the Army Of The Republic in some fashion, given what went down at the shop.

CT-31-4912 ("Mags") is a heavy infantry clone trooper who's been serving since near the start of the war. He's lost many brothers to the clankers, as well as one of his legs. He hates working with droids and avoids doing so whenever possible. He's still a good soldier loyal to the Republic, so outside very strange circumstances he's not going to be sabotaging the mission, but when considering friendly fire or what sacrifices to make for victory, he doesn't really consider droids people. What sabotage he might do is usually limited to a low-stakes environment where not much is at risk and so he can afford to put the "petty" in "petty officer": handing out bull**** tasks, exercising malicious compliance, filing complaints about broken regulations - little things that make life a touch more difficult for the inorganic beings he has to work with despite not wanting to.
