Yes. The Bhaktamar Stotra is primarily devoted to Lord Adinath (Rishabhanath Bhagwan), but it also contains general reverence to all Arihants and Tirthankars in its broader devotional spirit.

So, in clear terms:

• Main focus: Adinath Bhagwan
• Also respected indirectly: All 24 Tirthankars, through praise of the qualities of Arihants

If you mean whether there is any other specific Tirthankar named in the verses, then the stotra is chiefly for Adinath alone.

In Jain tradition, Bhaktamar is considered especially the stotra of Adinath Bhagwan.
