while read line; do
  set -- $line
  person=$1
  shift
  printf "%s has {$s} items in his bag" "$person" "$*"
done < data.txt

this is a good use for subtr() and index(). 

awk '{print $1FS"has {"substr($0,index($0,$2))"} itmes in his bag."}' data.txt

output:

personA has {neta netb netc} itmes in his bag.

personB has {meta metb metc metd} itmes in his bag.

What about:

awk '{ items=""; 
       for(i=2;i<=NF;i++) {items=items" "$i}; 
       gsub(/^[ ]/, "", items);
       print $1" has {"items"} items in his bag" }' data.txt
