One issue may be your machine's Heap space is not adequate:

WARNING: insufficent heap memory

Please keep your questions on same subject in the same thread.

Thxs!
 

i hope i have sufficent heap memory

[root@localhost author]# free -m
             total       used       free     shared    buffers     cached
Mem:          3035        147       2887          0          0         39
-/+ buffers/cache:        107       2927
Swap:         1992          0       1992

This part of the log file suggests that you have a memory issue:

The JVM reports 247 MB but we recommend at least 768 MB +/- 20
Use your JVM's heap size option (like -Xmx768M) to set that size.
Will fork a JVM to get enough memory.

From the http://dev.day.com/docs/en/cq/current/getting_started/download_and_startworking.html
If using the command line, for a 32bit VM type:
java -Xmx1024M -jar cq5-author-p4502.jar


 

java -Xmx1024M -jar cq5-author-p4502.jar
Error: Unable to access jarfile cq5-author-p4502.jar

when i execute this command it is creating crx-quickstart directory , there are only 3 folders created "app,conf and logs".

Have a look at this blogpost regarding doing an installation from the command-line:

http://experiencedelivers.adobe.com/cemblog/en/experiencedelivers/2012/04/installing-cq5-from-command-line.html

My first guess is that it is either too low mem or disk.
