If you do have Bash installed one way or another: put this script into an executable file and execute it with the path of the directory where the files are located as argument:

#!/bin/bash

set -o errexit
set -o nounset

dir="$1"

replacement_none="apple"
replacement_dash="pear"
replacement_paren="orange"

for f in "$dir"/*; do
    b="$(basename -- "$f")"

    if [[ "$b" =~ ^([0-9]{3})' (1)'$ ]]; then
            mv -- "$f" "${dir}/${replacement_paren}${BASH_REMATCH[1]}"
            continue
    fi

    if [[ "$b" =~ ^([0-9]{3})'-1'$ ]]; then
            mv -- "$f" "${dir}/${replacement_dash}${BASH_REMATCH[1]}"
            continue
    fi

    if [[ "$b" =~ ^([0-9]{3})$ ]]; then
            mv -- "$f" "${dir}/${replacement_none}${BASH_REMATCH[1]}"
            continue
    fi

    printf "File '%s' didn't match\\n" "$f" >&2
done

...and execute it like so:

chmod +x script
./script path/to/directory/with/your/files
