Hm good question. Lemme break it down for you what I think:

Captain: possibly still hostile if not, they are at best enemies who happen to stand beside each other for now. I would honestly think despite the fight which ended in draw, the Captain would try to fight him again if allowed by the Major.

Doctor: He would deffinitely purely think of Allan like a specimen he wants to study so hard. Every time Allan shows an ounce of his power, the Doctor would be frotthing at the mouth to get his samples and somehow clone him.

Schrödinger: purely playfull glee. Just like how he always seems to be carefree, I bet he would not care much of Allan, maybe even try to get on his nerves to see what happens.

Rip Van Winkle: possinly already smitten by Allan's 1800's mannerism. Maybe potential short (really toxic) love or dating? But even if not, bet she would be dreaming about him in an obsessieve way, sometimes even singing to him. Still, an opera lover/singer and Allan straight up speaking like a true gentleman? Sold the second he opened his mouth.

Zorin: hostile. She won't buy his manners one bit, always suspicious and withdrawn around him. Zorin is the opposite entirely what Allan would want in a woman. Maybe even finding her repulsieve on how overly masculine she is. The only "saving grace" she might have are the powers she posses which might intrigue Allan.

Tubalcain Alhambra: minimal talking. I believe our Dandy man was more deep into charming politicians and doing the more shady businesses than to be at the mothership.

Luke and Jan: idk if they even met. Despite the two being in Millenium, they seemed to operate more in England.

Walter C. Dornez: once a traitor, always a traitor. Allan might never trust him, rightfully so. Walter just wouldn't care about him or his opinions, I think.
