Depending on the site activity and what steps you take to try and get your question reopened, reopening a question will typically take anywhere from a few hours to a few days.
It's important to note that reopen votes start to expire at a rate of one-per-day after 4 days of no new reopen votes, and a question needs 5 reopen votes by the community to get reopened. So you have a limited window of time in which you can get your question reopened after the first reopen vote.
Normally when trying to get a question reopened, I do the following:
Edit the question. Quite often the question was closed for a reason and could use an edit, and the edit bumps it to the front of the "active" page, so more users are likely to see it. If possible, leave a comment as well explaining your edit so users that see the closed question know it's been modified prior to the reopen attempt.
Wait a few hours. The new Reopen Queue is almost always empty, so any question that shows up there is likely to get handled by reviewers quickly. If a question gets 4 more Reopen votes, it will be reopened, although if it gets 3 Leave Closed votes, it will leave the Reopen queue and you need to try other means to get the question reopened.
Ask for reopen votes in chat. Reopen votes expire after a few days if nobody else votes to reopen, so you generally want to try and draw attention to the question before they expire. Just be sure you're nice about it and be willing to accept that some other users might disagree with reopening it and argue about it.
Ask on meta to get it reopened, and explain your reasoning in an objective way. There's nothing wrong for asking for reopen votes on meta, as the users who can vote to reopen can't be everywhere at once. Just be sure that you are objective, reasonable, and can accept users disagreeing that your question should be reopened.
If the question still doesn't get the attention it needs after a few days and votes get close to expiring, you can also flag it for a moderator and ask them to reopen it. Be sure to include the reason why you think it should be reopened in your flag to make it easier for them to evaluate your question.
Flagging should only be used in cases where the original question closure reason have been addressed, and the only thing preventing your question from getting reopened is lack of attention from users who can vote to reopen. It should not be used to dispute a question closure where the community has already established that the current version of the question should remain closed.
I'm assuming you're talking about reopening this question, which already has 3 reopen votes. You've done a nice job editing it, so have a 4th reopen vote :)
