Agh! I was going to say that…
Many nice guesses there, but no hits so far. Time for the second image, I suppose.

Men of War: Assault Squad?
Viva Pinata.
Just kidding. Is it Brothers In Arms?
Nope and nope. Keep guessing. ;)
Graviteam Tactics (or whatever the name was before…)?
Ding ding! It’s Graviteam Tactics: Operation Star (previously known as Achtung Panzer: Operation Star). Arguably one of the best wargames ever made.
Juan, take it away!
Not sure if that’s an electrical circuit diagram or some kind of flight sim HUD. No guess for now. :)

It’s some sort of radio antenna on a roof of a building.
To me it looks like a Target Motion Analysis plot from a modern-era subsim. So ah… Fast Attack because it also looks old and pixelated.
Kentucky Route Zero? It seems like something that would have details like roof antennas and still be somewhat pixelated.
I think it might be the aiming assist on a rifle scope.
S.T.A.L.K.E.R.?
Some fun guesses, some closer than others, but none close enough.

That’s a swaying Chinese lantern, I think, but I’ve no idea on the game.
Edit: that glow suggests something quite stylised too. I dunno, Infamous: Second Son? Something like this. I think that’s too high fidelity though to be honest.
