Get custom Claim in jwt-auth laravel

I need help to figure out a issues. I am using lumen(laravel 5.1) for create web services for mobile app. I am using JWT for authentication and it returns a token.

First issue is that if i use same token from another system/device then it validated and returns requested information. I want that token should be valid only for that device/system from user get token.

Second issue is that i have added some custom claims in JWT token. I want to get custom claim value from token. I have found similar question Get custom claims from a JWT using Owin but didn't get how i use it in php.

Please help me to get solution.
