How can I damage npc and players?

Here it is only dealing damage to players, but I want to damage npc too, if only npc is around me it will only damage him, if it has the player and npc will deal damage together. And the same for the player.

~LocalModuleScript Damage

local plrs = game.Players:GetPlayers()
        table.insert(plrs, game.Workspace.Map.Npcs.Bandit:GetChildren())
        -- End dark particles

for i, v in pairs(plrs) do

        local char = v.Character

        if char then

            if v.Name ~= player.Name and (char.HumanoidRootPart.Position - pos).magnitude <= size/2 and math.abs(char.HumanoidRootPart.Position.Y - pos.Y) <= 7 then

                affected[#affected + 1] = v

            elseif v.Name ~= player.Name and (char.HumanoidRootPart.Position - pos).magnitude <= size then

                lessAffected[#lessAffected + 1] = v

            end

        end

    end

    --

    for i, v in pairs(affected) do

        local char = v.Character

        if char then
-- damage
for o = 1, 30 * speed do

char.HumanoidRootPart.CFrame = char.HumanoidRootPart.CFrame - Vector3.new(0, speed/30, 0)

char.Humanoid.Health = char.Humanoid.Health - (damage / (30 * speed))
wait(1/30)

                    end

            end

    end

-- Edit/ I just remembered that too.

~Script Damage

local char = player.Character

for i, v in pairs(char:GetChildren()) do

    if v:IsA("BasePart") then

        coroutine.resume(coroutine.create(function() --ModuleScript

            local deb = false

            v.Touched:Connect(function(hit)

                if game.Players:FindFirstChild(hit.Parent.Name) and not deb then
--Script
