            this.Controls.Add(pnl);

        }
    }

The definition of the panel should be once and outside (before) the loop.

I think you are looking for a FlowLayoutPanel which can support objects to be added one after one, confortably compared to a simple Panel (Location is automatic).

        string[] test = { "g", "x", "l" };
        FlowLayoutPanel pnl = new FlowLayoutPanel();
        pnl.Dock = DockStyle.Fill;
        pnl.FlowDirection = FlowDirection.TopDown;
        this.Controls.Add(pnl);
        foreach (string p in test)
        {
            Label namelabel = new Label();
            namelabel.Text = p;
            pnl.Controls.Add(namelabel);
        }

Then, think to investigate on your object properties - there are many - to let them appear as you wish. Among them:

• pnl.Dock is the way your panel is docked in the parent object (the Form), so I set to Fill so that there is enough space;
• pnl.FlowDirection is set to TopDown for the children to be from top to bottom (I figured that was your purpose with DockStyle.Top
