We have vendor device with public ip in internet.
IT need to talk to multiple servers inside the company network.
all the internal servers have private ip and connection need to come on different port numbers.
Currently I am allowing the incoming connection from vendor to one of our public ip address and using static nat translation
for destination address.
how can i do destination nat translation the single public ip address of firewall to the multiple ports and addresses?

While what @Otakar.Klier mentioned is right; I'd be amiss if I didn't mention this is a terrible security practice. You should be giving the IT folks access to a VPN (like the built-in GlobalProtect), limiting their access to the servers in question, and then letting them work like that. Exposing something to the outside via a NAT rule, even when properly restricted with a security policy and source addresses, is a terrible security practice.
I agree with you.
But in current scenario the end device does not support support windows it runs on linux and current version of it does not
support global protect.
as we are migrating this from Cisco ASA it is better protected with PA.
Also then end device only talks to few servers on specfic port.
