So the only icon not "solved" is the little yellow thing on this card above the faction icon.

And the icons at the top of the planet cards.
I think the small icon above the faction icon indicates either that the card is loyal (can't be taken as an ally) or is part of a signature squad -- notice that both of the cards in Cato's signature squad we can see have this icon.
The icons on the planet cards are the planet's assets. "Material" (red?), "Strongpoint" (green?), and "Tech" (blue?). You need to collect 3 of any one color by conquering planets in order to win the game.
"These symbols grant no abilities by themselves, but the first player to collect three planets sharing a common symbol dominates the sector and wins the game."
