damage reduction and multiple attacks

[Syriously]

If I use many shot with a longbow and hit a creature that has DR 5. Do I have to account DR to each arrow or just all in one collective damage pool then subtract DR?

Manyshot's description in the SRD (http://www.d20srd.org/srd/feats.htm#manyshot) states that DR applies for each arrow in the volley. Precision-based damage like Sneak Attack and critical hit only applies once, but other sources like elemental enchantments apply for each arrow separatedly too.

so what if I were able to do the same thing with daggers same rule apply?

Yep. The kind of weapon doesn't matter (unless the weapon has a property to bypass DR).

DR applies to each and every physical attack. (Weapon, Natural, Unarmed...)
If you shoot 5 arrows in one round at a creature with DR 5, it'll negate 5 damage from each arrow.
