If the indices are necessarily successive integers:

  links="A B C D"
  index=0
  for link in $links; do
    index=$(( $index + 1 ))
    something with $link and $index

If the indices are arbitrary:

  links="1:A 4:B 7:C 10:D"
  for linkinfo in $links; do
    link=${linkinfo#*:}
    index=${linkinfo%%:*}
    something with $link and $index
