Please find the details for your questions/query asked.

Q.I would like to get a statistics of how many users are hitting the websphere( active and concurrent users)

A: You can get the Total request report from  for the servlets and EJBs installed installed on a Application Server instance from built-in Tivoli Performance Viewer of the Admin Console
from the WAS Intergrated console

1. Monitoring and Tuning->Performance Viewer->Currenty activity
2. Start monitoring for the Server
3. Click on the server you wish to monitor

From the Summary report you can find the servlet,ejbs,threadpool, connection pool  hit count and response time

Q:I would like to know how to determine the memory usage.

A: The memory usage for the Application Server runtime statics can be viewed from built-in Tivoli Performance Viewer of the Admin Console.

1. Monitoring and Tuning->Performance Viewer->Currenty activity
2.. Select the Server.
3. Performance Modules
4. Check the JVM Runtime.You can view the statics in Table view or Graphical.

Q:I would like to know the most server logs location on webspeher server for troubleshooting.

A: The default location of the server logs will in the $AppServerRoot/profiles/<profilesname>/logs/<servername>


Q: I would like to know whether the application releases memory in a timely manner or not.

You can user performance viewer to view memory statics, if you want more detailed information on Java thread and process information you should use Performance Analysis Tool for Java from the IBM. You can get the tool from the below site.
http://www.alphaworks.ibm.com/tech/pat4j

Q: I also like to know the optimal way to tune the server for optimal performance

A: The optimal Performance can done by analysing the current application and their usage for Connection Pool, JVM utilization from the Tivoli Performance Viewer, You can even get an Advisory report from the Tool.

You can trigger Immediatestop/Terminate option from the admin console for WAS graceful stop.
You can use execute below command from wsadmin to stop Servers

wsadmin>$AdminControl stopServer <servername>  <nodename>  terminate

servername- Name of Application server instance
Nodename- Name of Node where the Application server instance runs.

No of java.exe process in the task manager is depends on how many WAS instances, nodes, dmgr runs.
For example if 1 dmgr, 1 node and 1 application server instance you can see 3 java.exe process.
