Fun and funny

1. "He's funny" and "He's actually a comedian" have similar, but not necessarily the same meanings. When you say "He's funny," you mean that the person has a good sense of humor, can make others laugh, or have a comical behavior. It doesn't necessarily mean they are professionals at comedy. However, when you say "He's actually a comedian," it means the person's profession or vocation is to perform comedy, typically in front of an audience. All comedians should ideally be funny, but not all funny people are comedians.

2. Yes, "This is fun" essentially means "This is enjoyable." If you describe an activity as "fun," you're saying it's something you find enjoyable, entertaining, or pleasurable. It's a broad term that can refer to anything you like doing or something that brings you happiness.
