Well, it indeed is a good decision to remove the preloaded apps from your Micromax device. However, it may not be possible to remove them altogether. You may need to disable them.
Here are the steps to disable the apps -
1. Navigate to the Settings.
2. Choose Apps.
3. Look for the app you would wish to disable.
4. Tap on it. You will be taken to the App options screen.
5. Tap on Disable.
Done! You have successfully disabled the app. Please note that the updates to the app, if any, will be gone. If you want to use the app again by enabling it later, you will need to update it to the latest version. Repeat the same steps to disable all other apps you do not wish to keep.
To permanently remove the apps from your device, you will need to root it and install an app for removing system apps. If you are not an expert in rooting and associated techniques, it is not advisable to opt for the option.
Live....and Let Live!
