You've misunderstood the grammar: Lily sings, "it's hard" (out where?) "out here..." "Out here..." means "not at home, not in my comfort zone, out in the real world".

to agree with what someone is saying with enthusiasm.. specially when replying to a question by "yes".

I've never heard of "hard out" and I'm from the U.S ..... Perhaps you mean "handout" like new pieces of paper teachers give to their students.
