I don't know how far the manga has gotten but you're more or less correct. There are only three people in the world Kumoko cares about and its her loli sensei, spider grandma, and her vampire daughter. And elves basically caused...fucking everything, way more than you could ever imagine depending on where you are in the story at the moment.
Wait, does she care about the dandy wizard and the tsundere demon boy? I don't know. She's a spider, they eat their husband's head, she probably fancied them if that's the case. I mean, I wouldn't be surprised if she did. The wizard is totally her type and it seemed like a romantic sub-plot was about to play out with the demon boy.
