How to grab all the children of a model that all have the same name?

I have 5 parts in a model named "Part" and I don't know how to change the properties of the children. The ? is something I feel like is missing that needs to be fixed.

This script is for a window script, when it becomes 16:00 it changes the glass in the model to the items below.

glass = script.Parent:GetChildren()
while true do
	if game.Lighting:GetMinutesAfterMidnight() > 16 * 60 then
		wait(math.random(10,50))
		for i, v in pairs(glass) do
			if glass.Name == "Part" then
				?.Transparency = 0
				?.Material = Enum.Material.Neon
				?.BrickColor = Color3.new("White")
			end
		end
	end
	if game.Lighting:GetMinutesAfterMidnight() > 23 * 60 then
		wait(math.random(20,50))
		for i, v in pairs(glass) do
			if glass.Name == "Part" then
				?.Transparency = .6
				?.Material = Enum.Material.Glass
				?.BrickColor = Color3.new("Dark Stone Grey")
			end
		end
	end
end

I would appreciate it if I could get some insight on how to make this for script thing work.

? should be v.

glass = script.Parent:GetChildren()
while true do
    if game.Lighting:GetMinutesAfterMidnight() > 16 * 60 then
        wait(math.random(10,50))
        for i, v in pairs(glass) do
            if glass.Name == "Part" then
                v.Transparency = 0
                v.Material = Enum.Material.Neon
                v.BrickColor = Color3.new("White")
            end
        end
    end
    if game.Lighting:GetMinutesAfterMidnight() > 23 * 60 then
        wait(math.random(20,50))
        for i, v in pairs(glass) do
            if glass.Name == "Part" then
                v.Transparency = .6
                v.Material = Enum.Material.Glass
                v.BrickColor = Color3.new("Dark Stone Grey")
            end
        end
    end
end
