Just an idea. You can use the Console.CursorTop and Console.CursorLeft properties.

class Program
{
    static void Main(string[] args)
    {
        new Messager(1000 * 2.5f);
        new Messager(1000 * 3);

        while (true)
        {
            Console.CursorTop = 0;
            Console.ReadLine();
        }
    }
}

public class Messager
{
    Timer Timer;

    static int position = 1;

    public Messager(double interval)
    {
        this.Timer = new Timer(interval);

        this.Timer.Elapsed += (sender, e) =>
        {
            lock (this)
            {
                var cursorLeft = Console.CursorLeft;
                Console.CursorLeft = 0;
                Console.CursorTop = position++;
                Console.WriteLine("message from " + this.Timer.Interval);
                Console.CursorTop = 0;
                Console.CursorLeft = cursorLeft;
            }
        };

        this.Timer.Start();
    }
}
