How can you move all the children if they are tools from a certain spot?

local serverstorage = game.ServerStorage
local lighting = game.Lighting

for i,v in pairs(serverstorage:GetChildren()) do
    if v:IsA("Tool") then
        v.Parent = lighting
    end
end

This script gets all the children of ServerStorage and checks if it is a tool. If it is then it will put it in the Lighting.

Use :IsA(...) to check if something's a subclass of something else.

for i, v in pairs(something:getChildren())
    if v:IsA("Tool") then
        v.parent = game:GetService("Lighting")
    end
end

You would use a for loop

local tools = game:GetService("ServerStorage")["TheTools"] -- Assuming their in a folder

for i,v in pairs(tools:GetChildren()) do
    v.Parent = game:GetService("Lighting")
end
