I can't remember where my mains were and I seem to have multiple accounts, is there a way to view characters on each account before you activate ?
If your on a live server on these accounts just log in. They are free to activate unless you decide to pay. If your on a progression server the you would have to activate a membership to see the accounts OR If this is the same computer you had when you played there may be EQ Character ini files in your directory.
Like Cats said, log in on each of the accounts and just look on the different Live servers. If there are none on any of those, then all of your characters must have been on Time-Locked Progression servers which means you would have to subscribe to play them regardless.
Another useful tip is to use this link to recover all the accounts associated with an email address. https://account.daybreakgames.com/reg/forgotStationName!input.action They will send you a list of all accounts associated with that email. Helps tons.
