[gelöst] abbreviations from document 1582 Wolfenbuttel

[Festina_lente]

In this document, Wolfenbuttel 1582, I need some help clarifying the highlighted abbreviations.

https://www.arcinsys.niedersachsen.de/arcinsys/digitalisatViewer.action?detailid=v3033795

I have 2 problems:

On page 2, the first arrow points at Ifg (Ihr fürstlichen Gnaden). In most cases it is like that.
The second arrow points to something like Ifs. What does it stand for or is this just a strangely formed g?

What are the underlined signs? Sometimes they look like H & H combined, sometimes like H & E joined together.

Thanks in advance.

(and sorry for not posting in German, but I unfortunately am not very good at writing in German; I do understand it, so answers may be in German)

I am not sure but I think that the first "HH" could mean something like "Hoher Herr", used when the lord was mentioned the first time in the text, "HE" could be "Hoch Ermelter" which means something like "the high person mentioned before".
With the strangely formed "g" you have been correct: again it is "Ifg".

Greetings!
