Answer 1

In your click handler, cast the 'sender' parameter to a PictureBox and examine its Location.

void pb_point_Click(object sender, EventArgs e)
{
    var pictureBox = (PictureBox)sender;
    MessageBox.Show(pictureBox.Location.ToString());
}

Answer 2

Sender is your picturebox. Just cast it:

void pb_point_Click(object sender, EventArgs e)
{
    var pictureBox = (PictureBox)sender;
    MessageBox.Show(pictureBox.Location.ToString()); //Retrun location of another control.
}
