Is it possible to display player's usernames on a surface gui if they are touching a specific block?

Here's a example (i'd recomend use Region3 instead Touch Events)

There's model link if you had some issue MODEL

--Important: Your detection part must be more high than players avatar

local Players = game:GetService("Players")
local touchPart = script.Parent.touchPart -- your detection part
local surfaceGui = script.Parent.surfacePad.SurfaceGui -- your surface gui
local touchingPlayers = {} -- create a table to store players that are touching

touchPart.Touched:Connect(function(obj) -- when the part is touched
    if obj.Parent:FindFirstChild("Humanoid") then -- check if who's touched the part has humanoid
        if Players:GetPlayerFromCharacter(obj.Parent) then -- check if the object is a player
            if not table.find(touchingPlayers, obj.Parent.Name) then -- check if player name isn't already on table
            table.insert(touchingPlayers, obj.Parent.Name) --insert player name on table
             end    
            surfaceGui.TextLabel.Text = table.concat(touchingPlayers, ', ') -- concat all strings on the table
        end
    end
end)

touchPart.TouchEnded:Connect(function(obj) -- when someone has 'untouched'  the part
    if table.find(touchingPlayers, obj.Parent.Name) then -- check if is in table
        table.remove(touchingPlayers, table.find(touchingPlayers, obj.Parent.Name)) -- remove from table
        surfaceGui.TextLabel.Text = table.concat(touchingPlayers, ', ') -- update surface text
    end
end)
