My ,or mine
==============================================
The first answer is theoretically correct, but classical Latin did not usually use the genitive form of ego, the personal pronoun, to mean "my" - this was (99.9 times out of 100) expressed by the possessive pronoun meus, mea, meum. On the very rare occasions when classical writers used mei, it caused some degree of uproar among the Roman readers.
amator mei
None. It is irregular. Nom = ego Genitive = Mei Dative = Mihi Accusative = Me Ablative = Me
Noli oblivisci mei.
Rex mei mundi.
soror animi mei
Liberi mei vita mea. (Latin doesn't require a verb in this kind of sentence, but if you want one you can put suntin between "mei" and "vita", or after "mea", or in fact anywhere you want).
The Latin equivalent of 'My soldiers stay eternal' is Milites mei manent sempiterni [or aeterni]. In the word-by-word translation, the noun 'milites' means 'soldiers'. The possessive adjective 'mei' means 'my'. The verb 'manent' means '[they] are staying, do stay, stay'. The adjectives 'sempiterni' and 'aeterni' each mean 'eternal'.
