3-6. The 3 planet model would have gliese 581 b too hot, gliese 581 c in the habitable zone, and gliese 581 d too cold. The 6 planet model would have gliese 581 e, b, and c too hot, gliese 581 g and d in the habitable zone, and gliese 581 f too cold.
Earth is similar to Gliese 581 c, in that they both are the third planet from their sun. See related links for information about Gliese 581 c.

Gliese 581 g was discovered on September 29, 2010.
Gliese itself does not exist, but Gliese 581 is a red star.

Gliese 581 IS the system, D is the planet.
The temperature is not precisely known. If you read the Wikipedia article on Gliese 581 c, you'll find various estimates, based on different methods.

Gliese 581 is a red dwarf star and does not have an orbit as such. The term orbit is normally reserved for planets revolving around a star.
No. g liese 581c is a planet that orbits a star, Gliese 581.
No.
gliese 581 is a star system not a planet however two of the 3 planets there are debatable that one of them could support life
