Why do some texts use amīce while here it says amicus?

Amīce is the vocative form, used when directly addressing a friend (i.e., "Hello, friend!"). Amicus is the nominative form, used as the subject of a sentence (i.e., "The friend is here."). In casual greetings, you might still see amicus, but amīce is more precise when speaking directly to someone.

Yes! Salve is a very common greeting, so it's appropriate for everyday use. If you're in a group, switch to Salvete.

What if I want to greet a female friend? Should I change amicus?

Yes, if you're addressing a female friend, you'd typically use amīca in the nominative, or amīca in the vocative (the same in this particular instance) if you want to be more precise. Thus, you could say Salve, amīca to directly greet a female friend.
