Generally, yeah

I don’t think the trans man would /always/ be transmasc, what if they were something like rosboy?

But mostly, yes. And that dosent mean not all transmascs are trans men either

If they identify as transmasculine then yes

Typically yes

Yeah technically but I know some don't really wanna be referred to that way :)

Technically yeah cause transmasc means your gender is masc and it's not your AGAB

But yeah it also has to do with how they refer to themselves
