Just put it before the if guildie line to include the others. But you will then have to move the line starting with local nameplate = to the same place so you can access the nameplate object.

So instead of ..

if guildie[guid] then
            PlaySound(416)
            local nameplate = C_NamePlate.GetNamePlateForUnit(unit)
            nameplate.UnitFrame.name:SetTextColor(1,1,1,1)
            nameplate.UnitFrame.healthBar:Hide()
            print(name)
        end

It should look like this..

local nameplate = C_NamePlate.GetNamePlateForUnit(unit)
        nameplate.UnitFrame.healthBar:Hide()
        if guildie[guid] then
            PlaySound(416)
            nameplate.UnitFrame.name:SetTextColor(1,1,1,1)
            print(name)
        end

This essentially hides the healthbar immediately when they first are shown ( but wow may show it again during its update routine ) and then does the guildie check before setting the text color and playing the sound if it is a guildie.
