Found my own way of doing this just by removing and renaming files and folders.
If you go to usr/local/red5/webapps
here lies all the directories for viewing when you go to default port 5080 so I simply installed the applications I needed and then took everything out of there except those applications I wanted and needed to run. I took out all and placed it in a folder in /var directory named it red5_movedstuff in case I want access to further applications later on.Then I renamed the applications I am using in webapps folder and kept admin folder to access them but I renamed my applications and had to importantly rename also in WEB-INF for each application name change.
Now if someone goes to myip:5080 they get a blank page and by changing names of applications I've hidden my directories beyond that including list of streams.
