You can't have multiple cellular profiles on an Apple Watch.

Set up cellular on Apple Watch - Apple Support

On to the next part of the question: why cant i install different secondary dials on apple watch from 2 different primary dials

What do you mean by that?

What do you mean by "profiles"?

Your question isn't very clear.
