From what I recall of Squirrel girl's feats, it has been shown she can take down even Galactus, if her squirrels make contact. That said, I don't believe she has much in the way of durability feats. In terms of speed, I think she was able to keep up with Spidey. And given her lack of appearance, I figure that's her bare minimum. Of course I figure she isnprobably faster.
