I wanna explore Banaras/kashi and Nainital. From my point of view first we will go Banaras and we stay there 2 or 3 days. Then we will go to Kathgodam (nearest railway station of nainital) via Lucknow. We can explore Nainital city and other areas near that city like Neem Karoli Baba Kainchi dham ashram, Bhimtal, Golu devi Mandir and lots of nice places there. After staying 3 days at Nainital then we will go to Delhi. We can explore delhi in two days and then we back to pune
