I am planning to do chlorination on pilot scale. Its a mix of C2, C3, C4 & C5 alcohols with Iso derivatives of C4 & C5.

Objective is to recover C5 Chlorides for further use.

Need suitable best catalyst & operating conditions....Any experimental data if possible (Even for Pure alcohols will be OK)

Well, for tertiary alcohols, HCl will replace the the OH with a Cl, and for primary and secondary alcohols you can use SOCl2 and Pyridine.  Wikilink!

I agree for chemistry part  but for industrial production I was focusing on using Chlorine or HCL (Liquid) for cost reasons. Moreover handling of SOCl2 is very risky & demands higher investment.

I am not sure about pyridine. Is it possible usign Pyridine alone - what is the chlorinating agent in that case.

Also I need some idea about actual operating conditions at lab scale so that we can conduct lab trials.

I think he meant SOCl₂ and pyridine! Otherwise, as you say, you'd have to magic a chlorine atom out of the void...!
