I am not sure how far you can be off without damage, but I think it is at least 2 or 3 teeth (7.5 deg per tooth).

Good news, i got it roughly timed at least. Left off by 1 tooth, right off by 1 1/2. Not bad for doing it alone though. Before i made the mistake of leaving it at 45 BTDC when lining the cams up.

I am assembling 1990 S4 engine that a Porsche dealership disassembled. The WSM references copper colored links. I have only found one mark on one of the chains. Did something change on the chains in the later years?

I'll have to look much closer.

One chain has them the other, not.

The color of the links is immaterial, they're all the same metallurgically. I can't see the 'humps' on your cams in the pic you posted but if the humps are both pointing straight up and you have seven link endplates between the humps, you're good.

Yes the cast lugs are in the correct position per the WSM - so I am good to go.
