It looks as though you don¹t have sparse mode enabled on your serial interface on R2. If you do a show ip pim neighbor, do you have any?
For the R2-> R5 link, do you have a second Serial link that is connecting those two routers. In the IP expert books, that is usually the PPP link. If you are running pim on the PPP link, that would explain why you could ping .2 and .5 from R2 and R5.

I am able to ping both groups 225.0.0.2 and 225.0.0.5 from R2 and R5 but not from R6. below are the interfaces config and the output of the debug ip mrouting command. Thank you in advance.
