I don't think there is a default OpenLayers way of doing this (although I am happy to be proved wrong), but you could build one yourself within a standard 'single feature' popup. We've done something similar on our application Dorset Explorer 3.
We basically loop though all the results and build a list, each of them clickable with more information. Try it out and maybe you'll get some inspiration. Just go to the link, open the Layer Control (on the right, icon of two rectangles on top of each other) and turn on a couple of layers such as Rights of Way (In countryside folder), Counties, Districts (In Administrative Boundaries folder) etc. and then do an info search by clicking once at a point and it should return multiple results. You'll see they are grouped by Layer Name and list all features found at the point you clicked.
I know this isn't necessarily an answer but I hope it gives you some food for thought. It certainly wasn't going to fit in a comment!
