1. Is it possible to blend light frequensies from different sources
through a prisma?

Yes, but it's usually done using a diffraction grating.

2. Is it possible to create a mathematical model for the blending
process?

Yes.

3. Could such a blending process be used for performing simple
arithmetic such addition
4. Could it be developed further for performing all kind of logical
operations and arithmetic operations

Yes, but trying to do it all-optically is hard - you need non-linearity.
It's also hard to minituarise optical components compared to standard
electronics.

5. Is there a limit to how fast "binary" values can be received using
a single receiver "plank length" how many planklenghts can be received
and studied during one second?

Yes, there is a limit. Planck length has nothing to do with it. The main
limit is bandwidth. There will be a secondary limit due to photon number,
but this is not the main limitation. (There were a number of papers on
this limit in JOSA back in the '70s. Search for "information content" and
you might find.) Iirc, terahertz has been achieved.

Is it possible to bypass the speed of storage limits by the receiving
unit splitting signal.

Yes, and it is done. Wavelength division multiplexing (WDM).
