how to have different shows on apple podcast under one name

Just add episodes are required to each separate podcast in the same way as you did when you created them, and re-publish (upload) the feed. The fact that they are all under the same Apple ID doesn't matter. You don't need to go into Podcasts Connect to add new episodes, just add them to the feed. That's all you need to do. New episodes will appear pretty well immediately for subscribers but can take a couple of days to appear in the Store.

I'm not sure what your problem is. You have two quite separate podcasts - Kinda Funny Games Daily and Kinda Funny Gamescast and you are uploading different episodes to each. You can change the title of either should you wish. You can also add as many extra podcasts as you want (to clarify: a podcast is a 'wrapper' containing episodes: many people refer to individual episodes as podcasts and this causes confusion).

You seem possibly to be suggesting that each individual episode episode should be a separate podcast in itself, with its own Store page. This isn't a good idea: you won't get people wanting to subscribe to a lot of one-episode podcasts. They expect to subscribe to a podcast and then get following episodes automatically as they are added. And podcasts which are not update may in theory be removed (though in practice I'm not sure this happens).

So basically you can create as many podcasts as you like, and add episodes to the one which is relevant to the subject of the episode.

Incidentally the title which shows in the URL is irrelevant. You can make that whatever you want or omit it altogether when giving out the URL. For example

https://podcasts.apple.com/my/podcast/kinda-funny-games-daily/id1247343210

https://podcasts.apple.com/my/podcast/yet-another-podcast/id1247343210

https://podcasts.apple.com/my/podcast/id1247343210

are all the same.
