No. There are only 2 species of venomous lizards: the Gila monster and the beaded lizard. The Komodo dragon has toxic saliva, but this is from harmful bacteria rather than true venom.
sometimes, depends on the lizard

the blue tongue lizard uses its tongue as a defense mechanism. When a predator sees the blue tongue it thinks the lizard is poisonous, when it isn't.
there harmless
Most blue tongued lizards are not dangerous or poisonous- The bright blue tongue is meant to scare or frighten away predators- in Biology this is known as aposemitism (warning colors). Most animals have pink tongues, so When the lizard is threatened, it sticks out a bright blue tongue which is shocking to the predator- while the predator decides whether the lizard is scary or poisonous, this buys the lizard time to escape!
No symptoms, I eat them all the time, raw. they are not poisonous.
the blue tailed dosent have a blue tongue and the blue tongue lizard hasn't got a blue tail. :)
No, when a lizard loses its tail, the tail cannot grow into another lizard, even though the lizard can grow another tail. Lizards do not have the same regenerative ability as starfish.
Zebra striped tail lizard
No, Blue-Tongues have no venom or poison at all, they can only bite your dog, which will probably result in your dog killing the blue tongue. I have no idea why people think they are poisonous, but your dog will probably kill the lizard if they are together. Don't put blue tongues with dogs
Blue belly lizards, also know as western fence lizards are not poisonous, but can bite. The only poisonous lizard in the US is the Gila monster, which live in desert areas, such as Joshua Tree, San Bernardino and few in Death Valley.
If you are in the south it could be a juvinile 5 lined skink
