Jenkins Infrastructure: Maven, Gradel, Sonarcube, Masters and Slaves, Sellenium

Please create topics in Jenkins on how to create two or more Jenkins Masters/slaves, with corresponding worker nodes on same Jenkins dashboard.
Also include videos that show how build tools such as maven, Gradel are integrated into Jenkins, how sonarcube and sellenium or other code testing tools are integrated and how they function.
A troubleshooting video with common error messages or a referral link will be helpful.

Thank you
