Translated that means you want us to give you all of the answers.
1. Draw the structures. If the amine group is R-NH2 it is primary. RR'NH it is secondary amine while RR'R"N is a tertiary amine. For example, e, ethylamne is CH3CH2NH2 so that is a primary amne. n-propylamine is CH3CH2CH2NH2 also ia primary amine. Benzylamine is C6H5NH2 which is primary, etc.
