How do I make a customable banner instead of the plain black and black message? (Is it to hard?)

Here's my code. I want it to have different colors, text, flashing text, textbox, etc. Thanks in advance.

game.Players.PlayerAdded:connect(function(player)
if player.Name == "jmotoyama" then
local f = Instance.new("TextBox", game.Workspace)
	f.Text = "Never fear, Jm the FT God is here."
	wait(4)
    f:Remove()
	wait(1)
end
end)

game.Players.PlayerAdded:connect(function(player)
if player.Name == "qitsi" then
local f = Instance.new("Hint", game.Workspace)
    f.Text = "qitsi, the Tower Tormentor has arrived."
    wait(4)
    f:Remove()
	wait(1)
end
end)

game.Players.PlayerAdded:connect(function(player)
if player.Name == "Tentameans" then  
local f = Instance.new("Hint", game.Workspace)
    f.Text = "Tentameans, the center/flat God has arrived."
    wait(4)
    f:Remove()
	wait(1)
end
end)

game.Players.PlayerAdded:connect(function(player)
if player.Name == "EnterTime" then  
local f = Instance.new("Hint", game.Workspace)
    f.Text = "EnterTime, Best SF'er is here. "
    wait(4)
    f:Remove()
	wait(1)
end
end)

game.Players.PlayerAdded:connect(function(player)
if player.Name == "iHateDex298" then  
local f = Instance.new("Hint", game.Workspace)
    f.Text = "Stand in the fire, DPS higher. iHateDex298 has arrived."
    wait(4)
    f:Remove()
	wait(1)
end
end)

game.Players.PlayerAdded:connect(function(player)
if player.Name == "PestLine" then  
local f = Instance.new("Hint", game.Workspace)
    f.Text = "Hakuna Matata. PestLine has arrived."
    wait(4)
    f:Remove()
	wait(1)
end
end)

To do that, you should use GUIs. Hints are (unfortunately) deprecated, and not flexible enough for your needs.

Also, instead of connecting separate events for each condition, simply use:

if x then
	...
elseif y then
	...
elseif z then
	etc...
end

It's cleaner, and, from my experience, much faster.

EDIT: To do that, you would first make a ScreenGui in the StarterGui. Then, you should use TextLabels instead of hints. These need to be placed in every player's PlayerGui, in the ScreenGui. The ScreenGui is copied to the PlayerGui, in case you're wondering.

for i, v in ipairs(game.Players:GetChildren()) do
	local Label = Instance.new("TextLabel", v.PlayerGui.ScreenGui)
	Label.Size = UDim2.new(1, 0, 0.05, 0)
	Label.Text = "Insert text here"
	-- Modify other properties here.
end

I've also set the position to a decent value. You can see all the properties of the TextLabel here. For example, to change the background colour, we do this:

Label.BackgroundColor3 = Color3.new(1, 0, 1) -- A purple colour

I hope this helps.

Not experienced in coding. How do I put the GUI in? And also, how do I make the GUI center in minimized or maximized screen?
