can I name the first compund as 1-amino-4-methylcyclohaeaxne?
can i name the second compound as 1-amino-2-methyl-cyclohexane? why and why not?

Apart from a few typos(*), your names follow the IUPAC rules, while the ones in the picture do not. They might be common names for people working with methylcyclohexane and their derivatives.

(*) 1-amino-4-methylcyclohexane and 1-amino-2-methylcyclohexane
