Yes. If you go back far enough, all life on Earth shares a common ancestor.
Birds and reptiles share a common ancestor and are both classified under the larger group called sauropsids. Modern birds evolved from a group of theropod dinosaurs, while reptiles include various groups such as snakes, lizards, turtles, and crocodilians. Both birds and reptiles lay eggs and have scales at some point in their life cycle.
The presence of a similar skull structure and the presence of scales on their skin suggests that crocodiles and birds share a common ancestor. Additionally, their common ability to lay hard-shelled eggs further supports the theory of a shared ancestry.
Birds are neither reptiles nor mammals. They are a separate class of vertebrate animals called Aves. Birds share characteristics with both reptiles and mammals, but they have distinct features that set them apart, such as feathers, beaks, and laying eggs.
Snakes are related to reptiles, specifically belonging to the suborder Serpentes. They are cold-blooded animals that are closely related to lizards and share a common ancestor within the class Reptilia.
Snakes are close cousins to lizards, as they both belong to the same group of reptiles called Squamata. They share a common evolutionary ancestor and have similar characteristics such as scales and a forked tongue.
Reptiles and birds share enough common characteristics to be classified in the same clade called Sauropsida, which includes all modern reptiles and birds.
Crocodiles and birds share a common ancestor. This can be seen by comparing the internal anatomy of the two. Dogs and Dolphins also have a common ancestor. Their skeletons again are both distinctly mammillian. The ancestor of dogs and dolphins and the ancestor of birds and crocodiles will again share a common ancestor, but you will need to go much further back. I am not sure of the timescales but we are talking tens to hundreds of million years.
No, humans did not evolve from reptiles. Both humans and reptiles share a common ancestor from millions of years ago, but they evolved along separate paths.
300 million years.
No, fish are not monophyletic. The term "fish" is a paraphyletic group because it includes some but not all descendants of a common ancestor. It does not include tetrapods (four-limbed vertebrates such as amphibians, reptiles, birds, and mammals) which share a more recent common ancestor with some fish species.
And they are most closely related to crocodiles, which also came from archosaurs. This is what most people mean when they say that birds are reptiles, although technically, according to the phylogenetic system, birds, reptiles, and mammals all share a reptile-like ancestor.

yes they do in facts share a common ancestor.
Yes, if you go back far enough.

Yes, plants and animals share a common ancestor.
They didn't but they do share a common ancestor. Looking at fossils, scientists have determined that bird evolved from small carnivorous dinosaurs. Both dinosaurs and crocodiles stem from a group of reptiles called archosaurs.
