Eeee, I'm excited for him! I'm Mal. I've got Klaus Hargreeves here first from the Umbrella Academy, attempting sobriety but that's always more of a guideline than a rule.
Then Peter B Parker from Into the Spider-Verse, the Alpha Peter if you will, he's trying to look after the other spiders and bringing a bar and some pizza to the good folks of Starklandia as some of them affectionately call it.
America Chavez from 616 of course, she's from just before the beginning of West Coast Avengers. So she'll likely recognize Strange.
And Finally, the miniature version of the Sarcastic Asshole Supreme who is a little less asshole a little more awkward youth - Tony Stark from the now defunct Avengers Academy game. He knew a version of Strange so you know that might be a thing he brings up at some point, but his Stephen was also younger so that might be a thing he brings up too.
