Answer 1

if you call

Form1.ShowDialog(this)

then you'll be able to get a reference to the calling form with

this.Owner.Name

in the second form (Form2 in your case)

Answer 2

You can get a reference to any of the application's currently open forms by using the Application.OpenForms property. Forms in this FormCollection can be accessed by index like so:

var form1 = Application.OpenForms[0];

or by the form's Name property like so:

Form form1 = Application.OpenForms["Form1"];

Hope this helps.
