I'm a bit confused about their rendition of Alpha Centauri. Are the two bright stars supposed to be Alpha Centauri A and B, and the dim one Proxima Centauri? That doesn't seem to make any sense considering that A and B have a distance of more than 10 AU, and Proxima Centauri to the others a distance of thousands of AUs. Wouldn't one star, A or B, be really big, the other noticeably dimmer and smaller, and Proxima almost invisible in broad daylight?

I'd say even in the best case, we'd be screwed, if we could even exist at all.
Arcturus is a red giant. Oops, screwed.
Polaris, Vega and Sirius are all relatively young, short libed, very luminous stars. Screwed. If they were in our solar system, they'd be red giants or white dwarfs by now (I can't recall off the top of my head if Polaris is massive enough to go supernova).
Alpha Centauri is the best case scenario, and it's a triple star, the larger two are 1.5 and .5 the luminosity of the sun. If earth orbits the larger, scorched. If it orbits the smaller, frozen.
All assuming an orbital distance of 1AU.
