How to run multiple storm topology at the same instance?

I am learning storm.I have a doubt regarding the number of topology we can run at a time on Apache Storm.I have submitted two topologies on storm cluster but at a time only one topology runs.I need to KILL or DEACTIVATE the already present topology to run any new topology.

I am using Storm 0.9.4

Zookeeper 3.4.6

Kafka 2.10-0.8.2.1

I am running one instance of storm nimbus,supervisor and ui.

Do I need to run multiple instances of each?

What do I need to do to run multiple topologoies at the same time?

I am attaching the screenshot of my storm ui.

I was using only 2 supervisor.slots.ports(in storm.yaml).And setNumWorkers() in my topology configuration was also specified as 2.Hence,the topology which was running first was occupying both the slots. Now, I have set 5 supervisor.slots.ports and things are working fine.I am able to run multiple topologies at a time.
