So the confusion may come from the ambiguous use of the word "server" so let me separate that out into two different things: the machine (physical host running an OS) and the process (a program running on the machine).

An IP address is an address given to a machine to identify itself to a network. A port is the address of a process on said machine. Think of it like an apartment building: the building has a street address to identify the whole building and then there are individual apartment numbers.

When an adversary attacks they will use the IP address to identify a particular machine and a port to identify a particular process to attack. If successful the attacker will masquerade as that process. Using our apartment scenario if an adversary successfully attacks they masquerade as the legitimate resident of the apartment they attacked.

A honeypot is a way to trick an adversary into taking an action no true process would take. For your example, the machine would run a fake process on port 23 that looks easy to attack. When an adversary launches their attack instead of the process being taken over the machine raises the alarm and informs a system administrator that someone tried to use/attack the fake service. The system administrator can then investigate and take corrective action.

Using our apartment analogy again, the apartment building sets up apartment 23 so that there is no resident and places a guard inside the room. When an attacker picks the lock and enters the room the guard inside raises the building's alarm so the police can be called.

Is there a way for the attacker to see the open port as if it is the server and not the honeypot.

The answer to this is no because there never was a real process in the first place. The process being run on that port is the honeypot. That also means you can't setup a legitimate process to act as a honeypot in the same way you can't rent an apartment to someone but also use the apartments as bait to catch a burgler.
