Thanks for your time and consideration.
I want to alias www.example.net and www.example.com to www.example.org 
xxx.xxx.xxx.253 is the ip address for two A RR's that are assigned to example.org and www.example.org in the zone-example.org file.

Do I need the A RR from example.org in the example.net and example.com zone files?

No, its no required since ALIAS (CNAME) pointing to another FQDN (A record) which is having RR

In fact You can directly create Host(A) records pointing to www.example.net and www.example.com with above IP address if wanted to in example.com zone and example.net zone, in that case ALIAS is not required.
