Your first stop should be Nick England’s site at

https://www.navy-radio.com/

There are plenty of manuals, data sheets and diagrams there.

Since I don't know anything yet, please provide detailed assistance.

For the Teletype Model 15 that I have, how can I find information
about the polar relay, the pulling magnet, and the holding magnet?

Also, regarding the loop wiring, how can I determine if the wires are
connected to the printer and keyboard loops separately?

Thank you in advance for your help.
