the compound denotes the year of composition of your ms, expressed with the bhūtasaṃkhyā notation (the digits are represented by items usually associated with those numbers, see e.g. Salomon's Indian Epigraphy p. 173). The numbers should be read leftward (aṅkānāṃ vāmato gatiḥ) and in this way you will have: khacara (the nine planets=9), śara (Kāma's five arrows=5). As for yaṇa, I cannot give an answer, as I can't find a meaning for it, but for sure someone of this list can do better. Are you sure of the reading? I cannot visualise the scan! Leaving the last digit aside, the date expressed is therefore Nepalese Year 95x. Since the Nepali age starts in AD 879, your copy must belong to something between 1829 and 1839 AD: does it fit? You can find more details in Kielhorn's "The Epoch of the Newar Era", Indian Antiquary 17. For lists of bhūtasaṃkhyās, you can refer to Bühler's Indian Paleography pp. 84-86 or Kale's History of Dharmaśāstra vol. 5.1 pp. 701-703. I hope this helped.
