Be sure that you look at the colors as you have in pictures 3 and 4, so that the counter is perpendicular to the wall (which is representing for the cabinet). That's the way it is really going to look.

Of the ones you show, it looks like the simply white (#3) goes with the lighter tones in the countertop the best. At least that is how it looks on my monitor.

Simply White is simply the easiest white out there! I’d say it’s the most used for white cabinets.

Primer a section of wall, and then put your colors back there, and try your countertops by them. The paint is picking up the creamy yellowy color of your wall, so you cannot get a good viewing of which one would be the best. On my monitor, it looks to be the second from the left, but, since they all appear yellowy because of the wall, they are painted on, its impossible to tell.

Make foamcore boards with the sample colors...you have a bunch of whites on a white background, you can't get the full color this way. Move the sample boards around...low, high, all walls where cabinets and counters are going.

What did you end up going with?

I went with BM Snowfall White, based on my Glacier White Corian. The funny thing is, the cabinets turned out a tiny bit cooler than the actual Snowfall White, but I like it even better. It goes great with the Corian. I know what a hard decision it is to make, and it's very subjective. I took notes on how each color looked in different kinds of light (not just daylight or artificial, but also morning vs afternoon) and in my west-facing kitchen, Snowfall White stayed truest. Most of the other colors I tested looked a lot different under different conditions. I don't see it mentioned on here much. It must not be a favorite. Btw, I almost went with Chantilly Lace, but it ended up a little too cool for my Corian. Great color though!

You have picked very clean whites and obviously the counter top is not a super clean white. When you look at the little 2" samples many of the whites don't look white at all, but when on a large surface (Walls, cabinets) they really are white.

Try White Dove. It is a warm white that is not overly creamy nor overly clean/bright.

I also recommend that you paint a large sample of each color and not on your wall.

I use 140 lb water color paper - you can get it at Michaels, Hobby Lobby or on Amazon.

For whites I like to do 18x24 samples so I have a really clear idea of what the color will look like on a large scale. Whites are tricky and you need to be able to truly visualize the color.

Set a small table or something up against the wall and set your counter top material on the table with the white wall color against the wall behind it.

Then take the samples outside on a clear day about 2:00 in the afternoon and look at the colors in bright natural daylight. If it is off you will see it better in this lighting than any other lighting.

Baby's Breath or White OC-151. Nearly impossible to tell from photos online but anything that looks dirty or dingy when comparing whites means there's not enough difference in Chroma.

Baby's Breath or White will give you the room needed in Chroma. White is brighter than Baby's Breath - we know it's brighter because White has a higher Value than BB (circled in pink).

We use the word bright to describe how we perceive a quantity of luminance a.k.a. Value.
