These planets are huge gas giants. One is 14 times more massive than Jupiter, the other 7 or 8 times more massive. That places them in the range to become Brown Dwarf candidates.
Pluto is roughly 40 AU from the sun. Planet b here is 162 AU out, making it 4 times farther out from the star than Pluto is from the sun, and planet c is 320, putting it EIGHT times farther away. We know how cold space is around Pluto, and it will be considerably colder for these planets due to their distance from the star. The glow we see in the images is their own heat, generated internally by gravity compacting their gasses due to their great mass.
If they are or become brown dwaves, they may have a retinue of "moons" or "planets" of their own, considering their distance from the central star, for which THEY provide the heat and light. Any potential life-bearing planets in that configuration, however, would need to be pretty close to the brown dwarf, as they don't even generate the energy of a red dwarf star.
"Brown dwarves" are kind of a gray area - they are not massive enough to ignite into actual stars, but are too massive to be mere planets.

Diogenes was eating bread and lentils for supper. He was seen by the philosopher Aristippus, who lived comfortably by flattering the king.
Said Aristippus, ‘If you would learn to be subservient to the king you would not have to live on lentils.’ Said Diogenes, ‘Learn to live on lentils and you will not have to be subservient to the king.’
