Balaji is common name meaning youthfull 'so it can be referred to any youthful god ..
But reason behind that Lord Venkateshwara gaining that name is ,He is the younger to all Vishnu avators of that time and the Hill which he is residing belongs to Varahamurthi (Varaha avator )(Who is in deep meditation for several years there. Since Srinivas arrived there later to him he is called as Balaji (Young )'by Varaha. )
That Hill probably gained the name after the arrival of Balaji i.e Lord Venkateshwara 'in KaIiyug '.So it's a blooper
Its is said to fulfill the two promises made by Lord ram and Lord Krishna to two different womens ...He took the Venkateshwara form
1.Lord Ram promised the Maya form of Sita ,who has undergone heavy difficulties under Ravan during that time (According to some versons of ramayan ,The maya form of sita is the one who undergone such difficulties and th Main sita is guarded by Agni ,who returned her back during agni pravesh ).SO Maya (her name is Devaki according to Sthal puran)form request Lord Ram to marry her ...he promised to marry her in Kaliyug ...in a form of Venkateshwara..
2. During Krishna avator ,Yashodha feels very bad that she is not able attend any Of Krishna's marriages ,though he married so much womens ...So he promised her that she will again gain the motherly status for him in her next birth too and will be blessed to have vision of his wedding with Padmavathi(Maya or saya Sita 😆)
