Did some disciples get treated differently from others?
You've pretty much answered your own question here. Jesus had many disciples. At least seventy, probably many more. And different groups were certainly treated differently. The best-known select group were the Twelve, called the Apostles. They were given more detailed explanations of some of Jesus' parables, and other insights not given to others. Within those, Peter John and James were selected to be present with Jesus at specific intimate occasions, including the Transfiguration and the raising of a little girl from the dead. Those three would go on to be leaders of the church.
Is this favouritism?
I think that's your implied question. To see that, you really have to look at what it means to be selected. The Twelve, and within that group the Three, were intended to be leaders of the church. If you look at what Jesus means by leadership it is "to become the servant of everyone". The Twelve suffered and were all persecuted, and tradition has it that all except John were martyred. You can consider that 'privileged' if you like, but it's not a privilege many of us would jump at.
