So I'm struggling with connecting 2 different railing heights...
The one on the left is 180cm high, the one on the stair is 120cm high.
I've tried anything (from all seperate pieces of railing to juist 1 continous railing), but the railing doesn't want to folow the green lines...
When I draw a line in the sketch, and set it to flat (RED), it never folows the host at the bottom (and blue part is also flat), unlike what this picture on the autodesk displays...
If you select the sketch line at the base of the rail (the flat one), change the value to Custom Height (seen in the options bar), you can adjust it with an offset value. The rail should do what you want

Sorry I didn't see the bottom rail. The baluster can follow the change if the Base is set to host with an offset, not set to bottom rail. Then the bottom rail could be a different railing with the offset of the sketch line to have a negative number. There may be a couple of different issues with a couple of the balusters but this is probably the best Revit can do with railings.
Wait, can you explain with a little bit more detail? And maybe a screenshot of the sketch and/or different segments?
I'm in no way able to create a flat top and slanted bottom...
Basically edit and select the (bottom) sketchline (or split the sketchline), set this to flat in the ribbon, then if you need to correct the height also set that to a custom adjustment in relation to the specified height in the railing type. In your case you do need to adjust it, since it will start horizontal from the point of intersection, or move the location where the sketchlines are split - so shorten the bottom sketchline) Maybe also set the rail type's tangent joins to extend rails to meet (but if you don't make a custom adjustment it should do the trick also without.)
edit: Just reread the question, didn't understand it initially it seems. Actually you might need adjusted balusters without bottom rail. The railing hacks video should provide you with enough to go on hopefully...
I think you should have a look at using the railing baluster panel family: https://www.autodesk.com/autodesk-university/class/Designing-Custom-Railing-Panels-Revit-2017#video Check out around 40 minutes, it's a similar situation except you'd build the balusters in the panel family itself unless i'm overlooking an easier solution (ofcourse you could do some in place modeling or using curtain wall family ie.)
