Neocaridina cherries are quite small so their offspring are going to be quite a bit smaller. If the tiny shrimplets are small enough to fit in a fish's mouth they will be eaten, unless they are totally vegetarian fish.
Both corydoras and rasboras are omnivores so they would probably find tiny shrimplets a lovely snack.
Sorry to be negative, but I'd hate you to lose your shrimps thro putting them in with omnivores.
Some fish may be primarily vegetarian, but when push comes to shove will eat anything to survive.
If you want to breed the shrimp they should ideally be in a shrimp only tank - I wouldn't even put them in with larger Caridina shrimp for the same reasons as above.
