I am stucked in lostlorn keep. Is there any kind of map or solution for the teleport map i killed the winged demon as last thing, but does not find anything else to do or a way to leave this place

It has been 3 days so i am guessing you have found yor answer, but for anyone wondering the "trick" to the portals is to go back through the portal you just entered from.
Instead of teleporting you back to the previous room it often sends you to a new place.

If you're stuck on the first level of the Keep, you need to activate a thing in portal room with the Nightmare horse, you'll get a cutscene showing you the way down from the main chamber has unlocked. I can't post links, but you can look up a video called "Lostlarn Keep Portal Puzzle - Pathfinder: Kingmaker - Varnhold's Lot - Let's Play - 9" by a guy called BringItDon on Youtube, the room is at timestamp 20:29.

If you've cleared the lower level and can't figure out how to progress, SPOILER, follow the underground river all the way to the N-E corner of the map, and inspect the vine-covered wall, Cephal will make a comment on it. Then backtrack a bit along the river until you reach the flower patch, at which point Cephal will automatically make some comments and you can interact with it. When you interact with it you can tell Cephal to do some stuff which will move you along, but make a save beforehand.

Lower Level ... heck, I am in the "Upper Reaches" of Lostlarn Keep right now, and I have exhausted what I know how to do. I am NOT a puzzle person.

You mean that?

That hurts my eyes to look at but yes, that. I haven't opened up the new portal set yet.

EDIT: So, I went in, and thank you, by the way ...

I have explored the First World room (southeast)
... the two-pad study (center north) ...
... the long hallway (west) ...
... the three-pad room with the scene of the Taldans (north) ....

... this is in addition to the entrance to the complex leading to Ankou's prison, and the Iron Golem room.

There are many portals which are not "opened", and on the map you provided, there is no second "shield" ... let alone all of the places that are opened by them.

Okay, I realized that I never backtrackked on the long hallway (west), and doing so finally led me to the hellhounds, nightmare, and another panel (which I activated).

Okay, so the dweomercats, the elder earth elemental (and his pals) are gone. I had gone to the lower depths briefly to clear out (I believe) what is down there.

So, now I am back to spinning my wheels.
