Maybe with awk and string functions:

awk 'BEGIN{FS="START|END"}
     /START.*END+END/ {gsub(/_this_/,"",$2)
     gsub(/modi/,"MODI",$2)
     gsub(/a/,"4",$2)
     gsub(/s/,"5",$2)
     print $1"START"$2"END"$3 ; next}
     1' infile

Maybe with awk and string functions:

awk 'BEGIN{FS="START|END"}
     /START.*END/ {gsub(/_this_/,"",$2)
     gsub(/modi/,"MODI",$2)
     gsub(/a/,"4",$2)
     gsub(/s/,"5",$2)
     print $1"START"$2"END"$3 ; next}
     1' infile

Maybe with awk and string functions:

awk 'BEGIN{FS="START|END"}
     /START.+END/ {gsub(/_this_/,"",$2)
     gsub(/modi/,"MODI",$2)
     gsub(/a/,"4",$2)
     gsub(/s/,"5",$2)
     print $1"START"$2"END"$3 ; next}
     1' infile

adapted for lines without START/END pair and check for occurence of both
