Question

hi

Will i be able to replace the existing application with a new application to android market, if i am enhancing it with more features

Answer 1

Not entirely sure what you're asking here. If you're asking whether you can push an updated version of your app out to all of you're existing customers then the answer is yes.

Answer 2

Yes. Apps update all the time.

Answer 3

Yes, as long as it is the same package and the version code is greater than the previous one. You can manage this in your AndroidManifest.xml

....   
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.your.package"
          android:versionName="1.0" android:versionCode="2">

....

You can check this for reference in versioning your android app.
