Quick answer is "No, NFS only runs on the host system".

Long answer is; NFS requires rpcbind to function. rpcbind is dependent 
on a network stack. Jails do not have their own network stack, they use 
the hosts network stack. There is some experimental software to give 
each jail its own network stack but I sure would not deploy a production 
system based on this.
