The maximum recommended amount pounds of force when pulling cat5/cat5e cable?

Not more than 25 pounds.

Explanation:

If we talk to the makers of these cables, then you will find that they always insist that a force exerted on them should not be more than 25 pounds. And this is because the conductors used in these cables are not big enough and they are more prone to break. And this implies that, if force above 25 pounds is applied on these cables then they are certainly going to break. And this is not what is expected.
