Crossover to multiple agencies at the same time

Hello- I am getting 2 offers from 2 different companies and each job is in 2 different agencies.I have following questions:-

Can I have my crossover done to multiple agencies through multiple companies at the same time?
I don’t even know for if crossover will go thru so can I try crossing over to job with 2 different level of clearance. One requiring TS and another with TS/SCI or secret?
Will it create conflict on my record in Scattered Castle?
