Is Uncharted: Nathan Drake Collection have all games included in the disc? - PS4

So I saw that Uncharted: Nathan Drake Collection and Uncharted 4 online which is discounted. I was planning to buy it but knowing I have a slow internet connection and it is not good to be downloading all three games so the question is: is uncharted 1, 2, and 3 are already in the disc(Uncharted:NDC) like you can switch to any of the games like Borderlands The Handsome Collection or only 1 uncharted game is on the disc and the rest should be downloaded through dlc. I hope someone can answer the question. Aside from that; I’d also want to know if the games Uncharted 1, 2, 3, and 4 require internet to play coz I was planning to buy Uncharted: NDC and Uncharted 4.
