Ubuntu UFW 3x specific IP addresses only to access a specific port

I need to use UFW to allow only 3x different IP addresses to connect on a specific port.
Ex:
IP address [1] - 111.111.111.111
IP address [1] - 222.222.222.222
IP address [1] - 333.333.333.333
on a specific port. All other connections denied.
Any help please ?
Can I simply add 3x rules one after each other for each ip address to point at the port ?
Thanks

First lets deny all access:
sudo ufw default deny incoming
sudo ufw default allow outgoing
Now limit out inbound traffic to ip via these ports:
sudo ufw allow from 1111.1111.1111.1111 to any port 33
sudo ufw allow from 2222.2222.2222.2222 to any port 33
sudo ufw allow from 3333.3333.3333.3333 to any port 33
If adding a specific protocol to the rules above:
sudo ufw allow from 1111.1111.1111.1111 proto udp to any port 33
Now check your rules:
sudo ufw status
To delete these rules at any time:
sudo ufw delete allow from 1111.1111.1111.1111 to any port 33
