So, in Allies > Advanced Growth > Weapon Refinery, you'll see a list of units eligible to have their weapons refined. Right now it's a relatively small group, I think, but new additions are occasionally added from the older pool of characters, plus I assume any event characters are automatically eligible. In my case, about 16 of my 168 can have their weapons refined right now. I assume they also have to be 5*, and maybe also have their previous strongest weapon unlocked via Learn Skills, but don't quote me on that last part.
After that it's just a matter of resources. You'll need SP on the character in question, plus Arena Medals and Refining Stones, and sometimes Divine Dew for the more advanced stages of refining, but not all characters/weapons seem to need it. So a case could be made for refining everyone else's weapons first before moving onto the folks who need Dew.
Home > Quests & Missions has various ways to get these things aside from just the Arena or Tempest Trials or whatever, but Divine Dew, as far as I know, can only be obtained by refining other weapons.
As for the S skill slot, these I think are always Sacred Seal enhancements, so you'll have to level those up via the Sacred Seal Forge. Most of the mats for those can be found just about anywhere and in the training tower most specifically, but the Sacred Coins are kinda like the Medals/Stones and I guess mostly sourced from quests and events.
