Abhimanyu being heir is actually not specifically mentioned excluding Satyaki making him one.
Uppandavas were either from Dasis or from wives who decided to stay in their father's Kingdom.
Sarvang for example is mentioned neither in the war nor post it though Kashi supported Pandavas.
I think these kids were later credited as Uppandavas. They were definitely not of Draupadi+Pandavas
