Meccy

Hello folks!
I have some lore/story questions that are stressing me a long time:

1. Who was the first arc angel?
In s4-s5 it was said that michael was the oldest one
In S11 amara says that lucifer was gods first born.
Is that a mistake in the series?

2. in S4 anna says that only 4 angles have seen god.
I guess those were the 4 arc angels - but there is still metatron who has also seen god.
Was that also a mistake?

I hope you can answer me my questions
Thanks!

I think there are continuity errors within the show, which was based on Christian mythology but makes allowances when a plotline needs it.
