One ground is enough when it is correctly connected. Eighteen would be fine. I've never seen a second ground do anything for a phono. Good luck.

Normally the ground wire on a tonearm cable grounds the tonearm to the preamplifier chassis; the cartridge is grounded to audio ground via the cable itself in a single-ended connection. But in theory, if hum is still present, it might be a benefit to ground other elements, like the turntable chassis, back to the chassis of the phono stage. Perhaps that is what the OP wants to do. I do agree with you, however, in that I have never known that strategy to yield any worthwhile reduction in hum. It's worth a try, though, don't you think?
Oh yes, always experiment!

Thank you all for your suggestions and comments. I have reduced the hum significantly since my original post by re-routing interconnect cables and power cords, but the hum is not yet fully eliminated. Will continue to delve further until it's gone.
I have seen Grado Regards combos that always have some noise. The high output Grado and lower end Rega.
