The error messages from the script tell you everything you need to know.
The script cannot find wlan0. So you probably need to specify a different network interface. One that is configured and active. What is the actual content of the script you are trying to run?
I'm not a Kali user, but perhaps look up the usage information for the script. Maybe you can pass it a parameter that specifies the correct network device to use.
So perhaps try:
bash /usr/share/mana-toolkit/run-mana/start-nat-simple.sh --help
Otherwise you'll probably have to edit the script.
