Answer 1

There is no way where you can make them all stretch while using float, without setting a fixed height to all images. You have three options.
Set a fixed height on the image and use object-fit: cover to make it look like it's stretching, while in fact it's covering it
Use flexbox with flex-grow: 1 on the image (see this example, recommended!)
Adjust all images to have the same width and height, if they can be made uniform.

Answer 2

I am sure that the images have different resolution.
First 2 images have the same resolution, 3:2 for example.
Last 2 images have the same resolution, 2:1 for example, but differs than first 2 images.
Please try to fix the resolutions of images all the same.

Answer 3

Your images are not the same height/width, just like the ones I found you when I made you a snippet. So decide on which direction is important and use vh/vw and auto
