Custom Post Type

Hello, im trying to display 5 Recent custom post types on my home page side bar, which ive managed to do.

I also want to created a page to display all the 9 recent posts within that custom post type. (this is where im getting confused) Ive called the page template page-podium.php (my custom post type is podium, see link)

my page-podium.php is https://pastebin.com/Ld9FCz7J It kinda of works. it displays them but im having trouble getting the pagination to work, is it in the correct place? it seems to multiply the links over and over.

And lastly. when i click on the custom post type post to go to the actual page it says page not found, this is the bit im confused the most about, is it loading them via page.php or single.php? or do i need a page-podium-page.php or something?

Kind regards
Thomas
