If you want a list of the open forms, that is Application.OpenForms. You could iterate over this, using GetType() and checking the .Assembly to find those from a different assembly. Beyond that, I'm not entire clear on the question...

        Assembly currentAssembly = Assembly.GetExecutingAssembly();
        List
 formsFromOtherAssemblies = new List();
        foreach (Form form in Application.OpenForms) {
            if (form.GetType().Assembly != currentAssembly) {
                formsFromOtherAssemblies.Add(form);
            }
        }

If you just want to track forms you have opened yourself, then cache that instance. Or if you use "owned forms", you can just check by name:

    private void button1_Click(object sender, EventArgs e) {
        foreach (Form form in OwnedForms) {
            if (form.Name == "Whatever") {
                form.Activate();
                return;
            }
        }
        Form child = new Form();
        child.Name = "Whatever";
        child.Owner = this;
        child.Show(this);
    }
