Respawns occur every 72 hours, 10 days or 30 days. It all depends on what is respawning.
The other thing to remember, is the respawn timer sets the time where the game can reset the cell, but it does not have to. So, a non cleared area can respawn in 10 days, but it might be 15 days before it really happens. It just won't happen in 9 days. And, you have to be away from the cell.
As to Merchants, it is usually 72 hours for their inventory. As for their cells, not sure.
