@pathfinder, “May I know what are the sources of these stories? Am i able to find them in the tipitaka/ find their suttas, or who are they written by?”
Below, you can download the Pāli sources (five books in four volumns) of those stories (referred as Commentary [aṭṭhakathā]) usually ascribed to Bhikkhu Buddhaghosa. Also, download the “The Dhammapada: Verses and Stories” with Pāli verses and English Stories.
Pali texts: Dhammapadaṭṭhakathā, the Dhammapada Commentary in 5 volumes:
Dhammapadaṭṭhakathā H.C. Norman Vol. I Part 1 (1906)
Dhammapadaṭṭhakathā H.C. Norman Vol. I Part 2 (1909)
Dhammapadaṭṭhakathā H.C. Norman Vol. II (1911)
Dhammapadaṭṭhakathā H.C. Norman Vol. III (1912)
Dhammapadaṭṭhakathā H.C. Norman Vol. IV (1914) — published posthumously
This anonymous commentary is basically a collection of stories, of which about sixty are shared with the Jātaka Commentary, chosen to introduce, contextualize and explain the verses of the Dhammapada. It was apparently composed in Sri Lanka and its date is unknown.
