In Vedic Astrology (Jyotish), the term "Lagna" usually refers to the Ascendant—the sign rising on the eastern horizon at the time of birth. However, there are several "Special Ascendants" or Varga Lagnas used for specific purposes.
The Hora chart (D-2) is a divisional chart used for wealth analysis. Hora Lagna is a special ascendant calculated from sunrise. They are related but distinct concepts.
