Answer 1

Lucky number is correct.

An eponym is the name of a person, whether real or fictitious, which has (or is thought to have) given rise to the name of a particular place, tribe, era, discovery, or other item.

An eponymous person is the person referred to by the eponym. In contemporary English, the term eponymous is often used to mean self-titled, as in "Metallica's eponymous 'black album'". The word eponym is often used for the thing titled. Stigler's law of eponymy suggests that Eponyms are usually false, i.e., things are rarely named after the person who discovered or invented them. An aitiology is a "reverse eponym" in the sense that a legendary character is invented in order to explain a term. Although in actual usage there is some overlap, an eponym may be distinguished from a namesake in that a namesake usually includes a "sake" connection to the source name whereas an eponym name merely is derived from a source name without an additional sake connection.

In science and technology, discoveries and innovations are often named after the discoverer (or supposed discoverer) or to honor some other influential workers. Examples are Avogadro's number, the Diesel engine, meitnerium, Alzheimer's disease, and the Apgar score.

Proprietary eponyms  (brand names or trademark of a successful product, that has come into general use to refer to the generic class of objects rather than the specific brand type, without the exclusive rights to said product being lost by the parent company)  

There are also genericized trademarks  (brand names or trademark sof a successful product, that has come into general use to refer to the generic class of objects rather than the specific brand type, with the exclusive rights to said product being lost by the parent company, either due to legal action or inappropriate following of trademark law. Examples include Brassiere, Escalator, Touch-tone).
