6 Scorpios in the 1st house?

Hi all,

I'm new here, been trying to learn about aspects and houses so far but it's been difficult to understand.

Lately, I've just searched up my friend's bd chart and OMG he has gotten such a unique chart!

Personal planet>> https://ibb.co/WFfX6sQ

Personal aspects >> https://ibb.co/xH5CG0R

Apology if any of the question doesn't make any sense because I still don't understand about the whole thing.

He has SIX planets in Scorpio and all of them are in the first house, Scorpio are known to be secretive so my questions are:

1. Does having all of them in the first house makes him more outspoken and speak without filter?

2. Does stellium in the 1st house make him vain person who only thinks and focus on himself?

3. Having pluto in Scorpio and in the 1st house, what would be the karmic resonance on this? his hidden enemy is himself?

4. He has sun square saturn, would that make his life more difficult though he has so many other positive aspects?

5. As a lover, does this indicate a selfish lover who thinks about himself the most (first house stellium) or does this indicate possessive, controlling lover due to his 6 scorpio planets in the chart?

6. Having many planets in the first house, does that mean the focus on his life will only be about himself?

I don't know where to start to read this chart but I've never seen such unique chart, appreciate any additional info related to this chart.
