I'm not a shrimp expert, I just have red cherry shrimps and have had amanos in the past. When I first got the cherry shrimps I had trouble keeping them alive, but then someone who was an expert gave me a lot of advice which I pass on
So many of the coloured cherry shrimps are all the same species, selectively bred to get those colours. Your red and yellow shrimps are both cherry shrimps, Neocaridina heteropoda, and will interbreed.
The third photo, red and white shrimp, could be another cherry shrimp with the common name red rili, or possibly a crystal red shrimp. Crystal reds (and crystal blacks) are Caridina cantonensis, a different species which needs soft acid and very clean water. I can't tell which it is from your photo I'm afraid as I have never kept crystals or rilis. In all the photos I have seen, the white part of rilis is semi see though while the white of crystal shrimps is opaque.
Depending which it is, it can either breed with the red and yellow shrimp (rili) or it needs different water parameters from cherry shrimps (crystal)
The last photo looks like a tiger shrimp, Caridina cantonensis, which again needs soft acidic water though is more tolerant than crystal shrimp. If the red and white shrimp is a crystal, they don't interbreed with tigers. (I wonder if they are actually different species but the taxonomists haven't separated them yet?)
As seangee said, the different colours of cherry shrimps will interbreed. Wild cherry shrimps are a brownish colour and the red was the first to be developed by selective breeding. The other colours are were produced later by more selective breeding. If the different colours breed, most of the offspring are the original wild colour. In your photos, the red and yellow are females currently carrying eggs (they are said to be berried because that's what the eggs look like)
Crystal shrimps and rili shrimps are variable in the amounts of red and white. Specialist breeders assign them to different grades depending how close they are the the "ideal" patterning.
