As I told you, am I new in lenses and I know that I will be learning during my progress. I have the idea to begin with one or two cheap foto lenses just to play with. May be I will then try find a place where I can rent and try out some of the better lenses.
before I buy my own.
I think is clever to start with some used, cheap lenses to get some experience. So go for it. You can always sell them later for only a little loss.

But I can't find the NON XEEN kit to 800$ or anywhere, or close to 800$. And I do not know how to say it. But in several forums do I read about, what I will call the missing quality control at Rokinon/Samyang.
From memory the Xeens cost around 2500 per lens not as a kit. The Xeens have better built quality but as far as I know are not better optical wise than the Rokinon Cine.
I can't say anything about their quality control as I lack experience with the Rokinons.

4. My first camera was a Sony Trinitron tube camera connected to a betamax recorder. Later i got a Full size VHS camcorder at work. And then I had a Sony Handycam DCR-TRV900 with 3CD I used for several years. It was a nice camcorder.
It have been much on and off. But now I want good 4K 50fps recordings.
I don't wanna talk you out of the UM46k - but are you sure have a good idea of how different shooting with this type of camera is - compared to the cameras you've had used before? And how huge file sizes of 4k 50fps will get? We are talking of 10 GBytes per minute here. You need large harddrives and a backup strategy.
And the rigged camera is heavy despite being called "Mini" and consumes ~45 W of power. But the footage quality is fantastic.

You will need an expensive head/tripod - the heavier the camera the more expensive tripods get.
Shoulder mount alone won't work, you will need some handles too.

With photo lenses zooming wouldn't work anyway as they are not parfocal, which means they can't hold the focus while zooming.

Or will it be better to buy one new Rokinon/Samyang NON XEEN Cine to start with. It can then be either a 35mm, 50mm or 85mm?
The 70-200 2.8 would be a nice start but you need to compliment it with another focal length range for wider shots. 70mm is quite narrow already.
I just tested a very cheap lens I have lying around with my UM46k and it works ok: Canon EF-S 55-250 4.0-5.6 IS II
Image quality is not great and it needs 1-2 stops more light than the 70-200 2.8, but it costs next to nothing.
For the wider angles you could get a Tamron 17-50 f/2.8 which is dirt cheap for what it delivers.
