Dont worry...you ll be ok. First off, you might get lucky and they drop off your reports now if they are close enough anyway...(although it is not recommended that you try to remove accurate information). Technically they can be relisted until the 7 year (or 7.5 years as some here would argue) is up, but even if you make a mistake and they come back verified, that doesnt allow them the right to extend the time on your reports. If they are still there after the actual 7 years, dispute again. You ll be ok.
As for the CO or CA, the 7 year reporting time is the same for any negative information with a few exceptions (liens, renewed judgements, BKs etc...).
SO, worst case is they will fall off when they are supposed to or you will have to redispute. Best case, some of them will come off early for you!
