I shall explain the difference between name, patronym/matronym, terranym and epithet here.
Name is a person's given name, given in namkaran samsakara.
For Pandu's second son it was Bhimasena
For Pandu's third son it was Arjuna
For their wife it was Krishnaa
Patronym means the title 'son of Mr'
Matronym means the title 'son of Mrs'
Epithet means a title given to a person on their unique ability/ something that they are famous for
For Pandu's all sons it was Pandava which means son of Pandu
For Pandu's 3 sons from his first wife Pritha, it was Partha.
So Yudhishtir Bhima and Arjun were Pandav as well as Parth. They were also called Kounteya because Pritha's father's name was Kuntibhoj so she was formally addressed as Kunti too. But her name was Pritha
While Nakul and Sahadev were Pandav and madreya. Epic does not Madri's given name
So Patronymn and Matronym are like surnames that we have today.
Arjun is the name Parth is surname. And Bhima also has the same surname because he has the same mother
Arjun is not the only Partha Bhimasena and Yudhishtir are also Partha. Please read the epic specially war Parva for examples
Arjun had many epithets or titles unique for him like Vijaya Phalguna Dhananjaya Jishnu etx
similarly Bhima had Vikrodara because he had a lean belly like a wolf. Vikr means wolf udara mean belly.
We still follow this naming system in Hinduism during wedding yagnopavita etc.
The marriage ritual for a bride and groom begins with their introduction just like in Mahabharata times.
