The fact that these rollovers went to separate Roth accounts is irrelevant. All of your Roth accounts are treated as one combined account for tax purposes.
Yes, you can combined these Roth IRAs into one. You must do this by nonreportable trustee-to-trustee transfer, not by distribution and rollover, otherwise you would violate the one-rollover-per-12-months limitation.
Because you are over age 59½, if the first regular Roth IRA contribution you made, if any, was for some year prior to 2020 or your first rollover deposit into a Roth IRA occurred before 2020, any distribution that you make from any of your Roth IRAs is a qualified distribution, no tax or penalty.
