What setting should I use on my Nikon D3100?

What settings should I use to get a nice white balance like these photos? Thanks!

Manual and learn to custom set your white balance per image.

I did not like some of that faded post processing on several of those. The easiest way is to set a custom WB. Or you can use a preset WB, your bride in the shade had a very blue dress. Setting the WB to shade would have warmed the tones quite a bit. Or you can set your white balance on auto and shoot in RAW. Then you can change the WB as necessary. In post processing. I had an answer ready for your other question which was already closed by the time I finished typing it. Let's just say it is good for you to learn WB among other basics.
