Consider who you are getting your advice from (myself included). Are these DJs guys that are self confident and aren't easily made jealous by the mention of another man's name? Are THEY seeing multiple people or ANYONE? Probably not on both counts. I may even hazard to say that they had been burned previously by someone they were dating.
Given all of that, you need to determine for yourself your specific comfort level. Also, that different DJs see dating differently. I may go out with several women but I will only date 1 or 2 and only if I feel that either merits some type of commitment. Too many times a guy will meet someone and after 2 or 3 dates they want to start dating exclusively and make a commitment. Does he know her well enough to have a viable LTR? Probably not.
That's why I will date a couple of women at once so I can easily guage which one I would want to commit to. This may take several weeks or several months since a ton of variables come into play.
I'll put it like this, think of having a meal of a sample platter. You have several small portions of things to eat, some you may like, some you may not. You may eventually order 2 or 3 things of the 6 or 8 that were on the platter. During your next visits you try one of the 3 each time then finally you get to just ordering you 'usual,' the one you enjoy the most.
So I say 'go out' with tons of women, 'date' the small group that has the most potential and finally 'commit' to the one that you are most comfortable with. Understand that this is only if you want to commit to one. If not, knock yourself out with going out with a entire herd, just don't expect any type of commitment in return. It's not fair, is it?
