I setted now 3 relays each without using any relay for two tasks. So any relay only serves to eighter write, read or direct message in my coral app now.

Only the client, although you'll want to make sure your relays support the kinds of content you'll be sending to them

Ok. How to verify this? Throuh the NIP’s they offer? Because most relays are not putting this in their description with human readable words. Would may be great, if the client can help with translating some technical stuff into a human readable one. What you think?

It's an unsolved problem. Many relays have a webpage you can visit that explains their policies more thoroughly, for example nostr.wine. nostr.watch is also a useful tool, but right now it's a pretty trial-and-error process. It would be nice to improve.

The first week of my #coracle I was running with 3 relays each. For no type the same relay and tried to avoid any popular relay besides mostr. There I often did not get all notifications. Now I added the damus and nos.lol relay to as reading. With this setup I seem to see all (hopefully). 🙌 Hopefully some day in the future, we can use all inpopular relays and still see all notifications and reach all followers.
