the rule of RR is

Client to non-Client
Client to Client

but non-Client to non-Client is not going to send updates.

R2 and R5 will be clients mean for example

R3

nei R2 remot 100
nei R2 route-reflector-client
nei R5 remot 100
nei R2 route-reflector-client

R4
 nei R2 remot 100
nei R2 route-reflector-client
nei R5 remot 100

nei R2 route-reflector-client

R3 and R4 here are servers so they will send only to the clients and if
there will be an update from R2 to R4/3 it Will not be sent to R1 as both
R4/3 and R1 are non-Client.

I think I am going to Dynamips it just to see that what i am saying here is
true on reality but as far of the rules that is how it should act.
