After reset.

Initial it asked me to accept these.

I had to accept all those. No other option.

Don't know why ,but I got 1.05gb of apps and 1.48gb of others. 

Where did these come from?

[trep]

Yeah. But if I leave them, I couldn't proceed further. Even though they mentioned it optional there.

You can proceed by accepting only the above two conditions license and privacy policy by tapping on the ticks near them and unchecking the 3 ticks below.
I think the 1 GB apps are system apps.
