its just called a first point.
Fore hand, back hand, and a serve that scores a point is an ace.
In tennis, a service is when one opponent hits the tennis ball over the net into the opposite box. It's how tennis players start the point. If you miss the first serve, you get to serve again, but if you miss that, the point is over. Your opponent won that point. If the ball hits the net before bouncing over, it is called a let.

No. If the server wins the point at deuce, it is advantage-in for the server. If the server loses the point after deuce it is advantage-out.
A legal serve must begin any conventional point play.
If you received the first point then you say: 15-love If you lost the first point then you would say: love-15
Overhead: An overhead stroke is any shot besides the hit that the ball hits the racket’s long axis close to vertical. The point of contact between the ball and racket with this stroke is typically above the players head. An overhead stroke can be used to hit off an opposing player’s lob stroke.
If at any point in the game where the receiving team has a break point (or Advantage in Ad-Scoring after a deuce), then it is called a break point.
