are these polarized or non-polarized?

All electrolytic capacitors are polarized indicated by a "+" symbol or band. This must be observed when replacing an existing electrolytic. I surmise from your question that you should do some research on line. There are many informative sites. Even Wickipedia.

What do the numbers mean (e.g., 4x7 and 5x11)?

It indicates the physical size of tha capacitor, diameter and height.

Generally speaking, electrolytics of this size are rarely certified as “low ESR. Usually they have higher voltage ratings and higher capacitance values. That said, I would say “no.”
