Hello!
I strongly recommend you to read Frame-relay documentation and focus on point-to-point, point-to-multipoint, hub and spoke, FR PVC and maps.What you ask here is not a solution to a problem but somebody to teach you Frame-Relay.
All your questions will have fine answer after you read some FR documentation. Here is good starting point: http://www.ciscopress.com/articles/article.asp?p=170741 but there is a lot of documentation online.
Cheers,
Calin
