Answer 1

You can use JSON Path Assertion available via JMeter Plugins project like:

• Given you need to check whether departureCity equals "Bengaluru, , IN - Kempegowda International Airport
• Add JSON Path Assertion as a child of the request returning your JSON response

• Configure it as follows:

  

• If everything is fine the result will be successful

• If expected value won't match the actual the sampler will be marked as failed:

  

JSON Path Assertion can be installed using JMeter Plugins Manager

Answer 2

Just add response assertion in your HTTP request and add all JSON responce in Pattern to test field
