The best way is to set seperate browsers and create your gmail id’s there in order to get your seller central logged in that browser, you can’t login 2 seller central in a same browser.
you better use different emails and bank account information for each seller account. you can make and plan different strategies for different account and work accordingly. Track prformance on everyday basis and stay organized, that;s how you can effectively manage multiple accounts and grow your business on amazon.
