write_aliases_script.sh

#!/bin/bash

printf "#!/bin/bash\n\n" 1>script.sh;

alias | grep NAME |
grep -o "'\(.\+\)'" |
sed "s/'//g" 1>>script.sh;

chmod +x script.sh;
# uncomment after testing
#./script.sh;

output

$ ./write_aliases_script.sh 
$ cat script.sh 
#!/bin/bash

ping google123.com
ping google321.com

Using eval you can make it run but be careful to not to invoke risky aliases:

eval $(alias | awk -F "'" '/NAME/{print $2}')
