This gives the output you suggest.

I have marked the places you should insert your code, they are inside the if statements containing the regular expressions you posted.

Code:

nawk '

BEGIN {FS = "\t"
    printf("%s\n\n", "Starting to read the config file")
    num=0
    bucle=0

}


/CACHE SIZE{/,/}/ {
    if ( $0 ~ /CACHE SIZE{/ ){
        printf("%s\n", "for CACHE SIZE:")
        next
    }
    if( $0 ~ /}/)
        next
    split($0, a, "=")
    printf("%s\n", a[2])
    if(  $0 ~ /^cache_size=[0-9]*[K|M|G]/ ){

        ## YOUR CODE HERE
        printf("%s\n\n", "Instructions for cache")
    }
}

/CRONTAB{/,/}/ {
    if ( $0 ~ /CRONTAB{/ ){
        printf("%s\n", "for CRONTAB:")
        next
    }
    if( $0 ~ /}/)
        next
    split($0, a, "=")
    printf("%s\n", a[2])
    if ( $0 ~ /crontab=[0-9]*|\*\t[0-9]*|\*\t[0-9]*|\*\t[0-9]*|\*\t[0-9]*|\*/ ) {

        ## YOUR CODE HERE
        printf("%s\n\n", "Instructions for crontab")
    }
}

/POLITICS{/,/}/ {
    if ( $0 ~ /POLITICS{/ ){
        printf("%s\n", "for POLITICS:")
        next
    }
    if( $0 ~ /}/)
        next
    print
    if ( $0 ~ /^[0-9]*[\%|M|K|G][C|F]\t[A-Za-z|\,]*\t[\<|\>|\=][0-9]*[K|M|G]\t[0-9][0-9]\/[0-9][0-9]\/[0-9][0-9]\/[0-9][0-9]\/[0-9][0-9][M|K|G]$/ ) {

        ## YOUR CODE HERE
        print "Instructions for politics"
    }
}
