Is it necessary to deploy each webapp in a different
If NO, how do I deploy all the webapps to the same instance. I face errors related to Perm, memory, scoket,etc.
If Yes, Then how do have multiple instances of Tomcat. I've been struggling to get through this.
Thanks in advance.

Yes, you can install multiple web applications (e.g. multiple war files) in 1 tomcat instance.
They must have different context root.
E.g. you can have localhost:8080/myapp1/index.jsp, and localhost:8080/myapp2/index.jsp
where myapp1 and myapp2 are the context roots.

Well I have deployed webapps in the similar fashion.
However, restarting tomcat leaves me with this
Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
Here is the process output

Your memory parameters are on the small side. About half of what you allow is going to be used up by Tomcat itself before any webapps even get deployed. Try bumping up mx to 512M or at least 384M.
