One google account many devices, can I have 1 private?

Hi all,

I have 1 google account for work and I have around 14 phones using this account (field worker phones). My work phone is also using this account however I want to add another google account and a number of different personal app accounts to this, all while using a dual sim. Would any of my personal information or logins transfer to the other phones at any time? If I turn off sync on all but drive and contacts would that prevent the other phones from receiving any prompts from my personal accounts?

I just want to be able to use a dual sim phone while ensuring my personal life doesn't leak into 14 other phones.

Thank you!
