Hi,
For Custom tab in Lightning environment please refer the following link:
https://developer.salesforce.com/forums/?id=906F0000000DEHGIA4

And to add the custom button on the page layout of the Lightning environment follow the following steps:
1. Edit the page layout in classic environment.
2. Add the button/tab in the Quick Actions in the Salesforce Classic Publisher section of the page layout.
3. Save the page layout and check-in Lightning environment.

Let me know if it solves your problem.

Many Thanks,
Sunil Rathore

Hi Khaviya,
You need to register the domain to see or create lightning component tab.

Thanks a lot you guys, that helped. Now the tab is visible in the app manager, but When i try to add it as a related list in another object page layout,its not allowing me to add. It says, "this related list cannot be displayed because it's not in the current page layout" . The forum said to check in permission set. But i dont know which permission set to modify. Any suggestions?
