This question requires matching inscriptions with the rulers or dynasties they are associated with. The Nasik inscription is indeed by Gautam Balashri (mother of Gautamiputra Satakarni). The Hathigumpha inscription is by Kharvela, the king of Kalinga. The Girnar inscription (also known as the Junagadh inscription) is by Rudradaman I of the Western Kshatrapa dynasty. The Aihole inscription, however, is not related to Pushyamitra Shunga.
