What is protocol? How can we define it in iOS?
A protocol is an agreed set of methods that are implemented by a class, when that class states it adheres to that protocol.
Those methods might be optional or required, this is set in the protocol definition.
Best course is to look here (requires sign in) and indeed read the whole of this guide as it a good starting point to understanding underlying design patterns in cocoa and objective-c.

Any way of doing the described in this question in iOS?
NSTokenField with mixed token/string input, possible?
As you probably know there are no equivalent Classes for iOS, anyway there are a couple of project around that do this pretty well, for example TITokenField. You can use the control as it is or grab just the logic behind.

I have multiple message mutators I want to add to the NServicebus pipeline. I'm using Structuremap as my IoC container. What's the proper way to register them with both Structuremap and NServicebus?
Found the answer in the examples.
Configure.Instance.Configurer.ConfigureComponent<Mutator1>(DependencyLifecycle.InstancePerCall);
Configure.Instance.Configurer.ConfigureComponent<Mutator2>(DependencyLifecycle.InstancePerCall);

Is collocation usually mean the location of the device? I am a little hazy on this subject.Or does mean general location.
I assume you mean CLLocation?. This is a class which represents location data generated from a CLLocationManager object.
Please refer to the Location Awareness Programming Guide, in particular the section on getting the user's location.

I need help on implementing a alphabetical scroller like in the music app on the right hand side and in the contacts app.
It's documented here : Populating an Indexed List
You'll need to implement tableView:sectionForSectionIndexTitle:atIndex:
You need to implement UITableViewDataSource:
http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UITableViewDataSource_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UITableViewDataSource/sectionIndexTitlesForTableView:
Specifically, the callbacks:
-sectionIndexTitlesForTableView:
-tableView:sectionForSectionIndexTitle:atIndex:
