Question about sponsor...

Hello

I just want to know how many sponsors are allowed for student visa? In my case I will have more than one sponsor mainly my uncle and my dad is this ok?
I will also get help from some of my relatives to finance my studies. Is it necessary to include everybody who will contribute even if they will just lend me partial money for my studies or i will just mention the main sponsors which is my dad and my uncle?
Last question would be is that is it ok that the sponsors will send me money and that i need to put it in a bank acct under my name or just tell the embassy that the money would come from them?

Tnx to those who would reply
