Octopuses have been known to nuzzle favored humans with their tentacles, and to spit water at disliked humans through their siphon. Do they really feel affection for their favored humans? I don't know. Discussions of this sort tend to devolve into debates about "qualia". What I do know is that octopuses appear to manifest signs of affection, and of contempt. And that I'd be honored to be nuzzled by an octopus, and I'd surely prefer that to being spit at by one.
