How to Access different form in the same panel in c#?

Question

My problem is how can I close form and show another form in the same panel In MainForm. For example I have 4 Forms this are MainForm, homeForm, Form1, Form2. MainForm Has one panel named panel1. So when you run the application it will show MainForm with panel, inside that panel first it will shows Up the homeForm that has 2 buttons access to other forms. And each Forms of Form1, Form2 Has one button named BackToHomeFormBtn and ones when I click the backToHomeFormBtn It will go back to homeForm. Help Please. I really need to resolve this problem.
