I'm starting to learn AngularJS, the tutorials I follow use the version 1.2.28, and it's quite different from 1.3.8. So my question is, should I:
Keep learning 1.2.28.
Try to learn 1.3.8 the hard way?
Wait for a new version?
I really don't know what to do!
Don't wait for the new version. See here a video on why:
http://gurustop.net/blog/2014/12/23/angularjs-1_3-1_x-angularjs-2_0-my-take
Angular 1.2.x would only be useful if you are targeting IE 8, and it's getting closer and closer to a dead end.
Your bet should be on the latest 1.x version. That's now 1.3.x and soon in ng-conf by end of January will be 1.4 (more about 1.4 at http://gurustop.net/newsletter/7)
The differences between 1.2.x and 1.3.x shouldn't be that big for someone starting. Mostly just new features and most heavy changes affect advanced users. The entire changelog is available at : https://github.com/angular/angular.js/blob/master/CHANGELOG.md
There are several documentation improvements in 1.3.x as well.

my next project is a pure angular application.my first task is to automate the UI after that the other testings comes.. and my question is that can we use selenium for UI automating a angular application and if so how can we do that .. if any references please let me know that..please help me by posting your valuable comments .. thanks in advance
Yes, it is possible. Selenium provides various element selectors with web driver for all browsers.
So as you are starting with new project, I will suggest you try adding unique and precise ids to elements which will help while writing automation scripts.
There are other frameworks too which are designed to target anguar app automation testing like protractor.
As angular have limited support for IE at some point you might get stucked with selenium where protractor will make your life easy.

I'm having an angular app built on angular 1.4 I want to update the app to angular 2 What are the steps that should I follow to do this.
Without breaking my existing functionality. Please let me know.
This is not a task to be taken lightly. You will find Angular 2 very different to Angular 1.x so you will need to spend time learning the new framework before you jump in.
That said, there are libraries to help this transition.
I would start here:
https://angular.io/docs/ts/latest/guide/upgrade.html
The answer would be really big, so I will just redirect you to proper ressources:
UPGRADING FROM 1.X
Preparing for and Migrating Applications to Angular 2
Seamless Ways to Upgrade Angular 1.x to Angular 2
Migrating from Angular 1.x to Angular 2: Upgrade Strategies
Of course, this list is not exhaustive, but I would highly advise you to make your own research and check the link I gave you (especially the first two links) to make it work.
I think it is a big task to change from angular to angular 2 framework. as there are many diffrence between them Please click here for more information

Which angular grid provides best performance in MVC API Application and great function for client to use?
ag-Grid is the best. I am the founder of ag-Grid, so you may find my answer biased. Hoewver I encourage you to look at the website and make your own mind up. You will see the following advantages over others:
1) Excellent performance.
2) Framework Agnostic, so will work with Angular 1, Angular 2, and if you decide in the future React, Aurelia, Web Components or Plain JavaScript.
3) Lots of features (you will see on website exactly what).

I'm new to Angular 2, I just want some useful links for learning Angular 2 with javascript(ES5), since I tried to find some useful stuff from google search, but there is no single place where I'll get basic information. So anybody knows about any kind of material like videos or demo samples, please post here, I really appreciate you responses :)
Here are some links, what I knows:
http://blog.thoughtram.io/angular/2015/05/09/writing-angular-2-code-in-es5.html
http://nicholasjohnson.com/blog/how-to-do-everything-in-angular2-using-es6/
https://daveceddia.com/dependency-injection-angular-2-es5/
This is a good hands on starting point, Angular 2 + ES6/7
https://github.com/blacksonic/angular2-esnext-starter
Basically as official suggested angular2 has good compatibility with typescript instead of ES5*6 may be thats the reasons why all the tutorials and articles were written using typescript but still if you wanna use angular2 using ES5 you can refer here :-
https://www.sitepoint.com/creating-components-angular-2-typescript-es5/
https://angular.io/docs/js/latest/index.html
https://egghead.io/lessons/angularjs-angular-2-hello-world-es5
also you can refer direct with your problems on stackoverflow and github issue
hope this may help you :)
I tried the official docs and they're very clear
https://angular.io/guide/quickstart

I would also want to know whether is will be of any use of not if I learn ExtJs?
I am a CQ5/Java developer. I work more on the OSGi level. But now the requests for custom components is too much so I am struggling with the ExtJs part that involves custom widget... Will learning ExtJs help me as a developer?
(Please provide helpful links)
CQ 5.5 also uses v3.4.0 of ExtJS on top of which the AEM Widget Library is built. You can find the release notes at /libs/cq/ui/widgets/source/ext/release-notes.html
The following Note is also available at https://docs.adobe.com/docs/en/cq/5-5/developing/widgets.html
CQ 5.5 is built upon ExtJS 3.4.0.
A similar question was answered 2 days back here.
The best source of info on AEM widgets is https://docs.adobe.com/docs/en/cq/5-6/widgets-api/index.html . I think there are some differences between AEM version and vanilla ExtJS.
