What makes a girl attractive?

Her confidence and ease with herself. Unafraid of physical self-expression. Nice features and a good body can also be "hot" but it's the confidence that goes with it that shines through.

What is the meaning of HOT?

Personally I mean hot means warm. So why do they call girls "hot"?

A: ... because in a boy's mind, they look like gold. The Word hot just means their beautifull

To me, the question is placed in category, "Sex", and it also speaks of "physical" hotness, so the answer would have to address those parameters - it would refer not just to "beautiful", but to 'sexually attractive' - a 'turn on', if you like.
