dirge is right.
From L-R in that picture it's Sea Clamp, Ram Horn and Cicadacon. And Unicron is also correct for the bonus Q.
Tarantulas once states that he and the Tripredacus Council are not descendants of Autobots or Decepticons and that they had different origins (hence why he didn't care about destroying the Ark and killing both Autobots and Decepticons board, whereas Megatron only wanted to kill Optimus Prime - he would never dare kill a Decepticon as it would cancel out his own existence) and Megatron once referred to Tarantulas as "Unicron's spawn," which by default would also make Unicron spawn of Unicron too. Whether they were directly created by Unicron or decendant from creations of Unicron is never specified, but Unicron is the correct answer.
