It’s just chai, so what you’ve already listed is sufficient especially for one or two guests. I’m more partial to samosay than pakoray because they look neater presentation-wise. But if you want to add more items, here are some ideas:
Namkeen:
Stuffed pastries such as samosay, patties, or spring rolls.
Cutlets
Aloo ki tikkiyan
Nimko (you can get packets of it from a desi market).
Sweets:
Halwa..can be a simple suji ka halwa
Gulab jamun
Rasmalai
Shahi tukray
Kheer
