Chivda and ladoo are the obvious ones, but there are quite a few Indian snacks that easily last weeks or even months without refrigeration if stored properly in an airtight container.
Namkeen itself is a big one here. Aloo bhujia, sev, chana dal and moong dal namkeen usually stay fresh for two to three months easily, sometimes longer depending on how it is packed. This is actually why namkeen is such a popular choice for gifting during festivals and for stocking up before events, since you do not have to worry about it spoiling quickly.
Mathri and shakarpara also hold up well, often lasting a month or more, since they are fried and dry with barely any moisture left in them. Same goes for chakli and murukku, both stay crisp for weeks if kept sealed.
Roasted chana and roasted makhana are another good option, simple, long lasting and require almost no preservatives to stay fresh. Papad, once dried and stored properly, can last several months too, and can be roasted or fried fresh whenever needed.
Khakhra is worth mentioning as well, especially popular in Gujarat, since it is thin, fully dried and can easily stay good for a month or two.
