Hi,
1.What are the IMS and RCS based clients available to test on Kamailio IMS/RCS server?
you can use the following android application:
https://rcsjta.googlecode.com/git/sdk-joyn/index.html
2.On browsing for Kamailio Installation,I found below 3 different links,please suggest me which one to be followed.
The 2 first links are IMS specific instructions, i think they complement each other.
The third link is a generic kamailio install from sources tutorial, that you won't need if you use RPMs or .deb packages.

3.From the first link above,I see there are separate steps mentioned to install CSCF nodes and HSS but where I find no information for setting up RCS AS(application server) module.Please let me know on this.
There is no RCS AS function in kamailio, this has to be a separate server. Unfortunately there is no freely available RCS AS to my knowledge. But fortunately, most use cases of RCS don't absolutely require an AS to work, only the groupchat scenario needs one.
