Excel _ Problem

Hi Team

I need to pass multiple username and password to perform End to End workflow and -All the scnerios are dependent on pervious senrios 

Question 1 : How to pass username1 & password1 from excel and perform scnerio 1 then logout the browser and then to perform senrios 2 -login with different credential and perform scenrio 2 then logout -- continues.....

Note : Complete End to End Flow should be in single main method 

I am able to split each scenrio into separate method but i am unable to combine all of them 

Please help me - Need idea to work on it

Example:

Scenrio : 1 

Username1 and password1

Method01 to perform

Senerio :2

Username2 and password2

Method02 to perform

Senerio :3

Username3 and password3

Method03 to perform
