Very nice link, sorry for the delay, the table in the NEC doesn't expand nearly as well as the one you posted.
Here's the deal:
The NEC and the table posted are based on a 40% fill factor. This may or may not be a requirement depending where you are and what the conduit is used for. This last code revision, the NEC exempted horizontal runs of communications cabling from the conduit fill requirements. I have no idea why, but they did. So if this is a sleeve from the equipment room into the drop ceiling area for your cables, I think you could look at 90% fill factor. However, if this is a run of conduit and has a bend in it, I would think it may not be considered horizontal cabling and the fill requirements may apply.
Back to the table, if you assume Cat5e at about .25 for area, and you have 5" sleeves, 40% will get you 163 cables per sleeve. If you were going to bump that up to 90% or so for a short sleeve only, you could get 408 cables in or so.
If you are looking for code and standard compliance, I would stick with the 40% to be safe, you would need three 5" sleeves.
Hope that helps, sorry for the delay in responding.
Good Luck! It is only my opinion, based on my experience and education...I am always willing to learn, educate me!
