Is the ball head on this 20mm ball mount

Can't measure the ball diameter because you can't un-thread the arm screw completely off.

Can this clamp to a flat surface or must it be a rod?

Yes and no. Super clamps are designed to clamp to photo/video pole systems, which are tubes. Notice the pincer-type jaws? That’s so the curvature of the clamp’s surface can have more contact —grip— with a pole’s surface. This is very much like a thumb and forefinger of the human hand. To make a super clamp —any super clamp— fit a flat surface the gap in the “elbows” of the clamp’s jaws must be made flat. Otherwise only the tips of the jaws —the pincers— will make contact and the clamp will pinch the material it is affixed to. To make a super clamp flat requires a fitted nylon, plastic, hard rubber, wood or metal spacer. When the clamp is tightened the force will transfer through the entire now-flat contact area to hold to the flat object. You can use the clamp “as is” to pinch a flat surface, but you risk an insecure clamping, crushing the object clamped, and marring the surface of the object clamped. I hope this helps!

What size phone will this fit? I couldn't find the maximum opening dimension of the phone adapter.

I found this, which appears to be the same model phone mount https://www.amazon.com/ULANZI-ST-07-Microphone-Samsung-Vlogging/dp/B07ZPR7WGH, and goes from 2.2 inches to 3.93 inches for the maximum phone width (side to side if the phone is in normal portrait orientation).
