how to implement club post type

I strongly recommand you to use ACF (pro if you can, usefull for the repeater) : https://www.advancedcustomfields.com/

You can easily add custom field and link them to post type, and link post type to each other (this answers your two first questions).

For the third, I guess it will depend how you could implement this
