Here's some info: https://www.fidelity.com/learning-center/personal-finance/retirement/roth-ira-5-year-rule
I've done 4 of them over the years. Personally, I found it best to open an individual Roth IRA for each one. 3 of them are now finished with the 5 year rule.
If they were all in one, I would imagine Fidelity would be responsible for separating somehow in the one Roth. This way, when I withdraw, I know exactly where I can and cannot withdraw from.
