Yes, all reptiles breathe using lungs. If they are underwater they have to come to the surface to breathe. Amphibians (frogs, newts, salamanders etc) are NOT reptiles. Amphibians often breathe through their skin.
Through their moist skin and lungs.
Newts have toxic skin, and feathery gills.
Amphibians are creatures which spend part of their life in water and part of their life on dry land. Frogs, toads and newts are all amphibians. They all start their lives as eggs. They hatch out as tadpoles which breath through gills. As they grow, they develop lungs and legs, and are able to leave the water and walk on land.

No. Fish breathe through gills and have scaly skin. They have fins and no true limbs. Amphibians breathe throgh gills during development stage then convert tro lungs. Most then grow limbs and have naked (no scales) skin. Examples of amphibians are frogs, newts, salamanders and toads.
Not necessarily - the Axolotl and newts both have gills - but they are not fish.
yes, like any regular lizard, newts have webbed feet.
Since frogs spend most of their lives in water there is a huge advantage to having a redundant system of getting oxygen. The need for a frog to be able to breathe without surfacing during the winter months makes "skin breathing" very advantageous. The use of lungs is effective when the frog is on the surface (especially when completely out of the water).
Reptiles breathe air through their nostrils and their mouths into their lungs. They don't have gills and if they swim underwater they have to come to the surface to breathe.(Amphibians ( frogs, toads, salamanders, newts, and caecilians) are not reptiles. Most amphibians can accept oxygen from water or air through their skin. They can also pump air into their primitive lungs using their mouth or throat to force it down.)through their noseYes they do.

No, this is called neoteny and is ot found in frogs. It is found in some newts.
Amphibian (meaning "both sides") are any cold-blooded vertebrate of the class Amphibia, comprising frogs and toads, newts and salamanders, and caecilians, eggs being soft and laid in water, the larvae being typically aquatic, breathing by gills, and the adults being typically semiterrestrial, breathing by lungs and through the moist, glandular skin.
