As you told you are facing problem to run kibana but you are accessing localhost:9200.
but it is elasticsearch server's port configuration.
Are you also facing issue with elasticsearch ?
as per your post i am understanding that your elasticsearch is not running that's why problem with kibana also.
for this share your elasticsearch logs also and which version you are working on?
>>> Can I use another port here?
You acn customize port for elasticsearch and kibana also by editing yml file for both(default port for elasticsearch is 9200 and kibana :5601)
