Hi,
You can install multiple odoo version in your machine, what you need to do is that run in different port number. This videos show how to run multiple instance of same odoo version :  https://www.youtube.com/watch?v=iUiTSPU9gHE

by referring to this you can install different odoo versions:

* download source code
* install requirements
* create db user and configuration file
* create service and run the odoo

Thanks
