maximum number RDF devices per RDF group
I have vmax250fx running powermax OS, the maximum number of RDF devices is 64k. I would like to know is there any limit for maximum number of RDF devices can be contained in a RDF group.

We use all TDEVs as RDFs as well, but when I provision a LUN I just assign it as Dynamic RDF without other SRDF configurations.
Where in this process do I specify the RDF group?

same characteristics but could have different load based on how many devices are using them. You specify RDF group when you create RDF pair.

when you create RDF relationship
symrdf -sid 1234 -f myfilewithsource_target_devices.txt -type R1 -invalidate R2 -rdfg 11

Please refer to the Solutions Enabler SRDF CLI Product guide for an explanation on the -f parameter. We are happy to help in the forums but you should really check out the documentation before posing a question here.
