Yes you can.
Download sysapp pusher.
Now change your proxy to 103.13.29.118 and port to 8888.
Go to sysapp pusher and click on the app you want to download. It will show you the install button.
Now press the windows button and go to wifi settings and change the proxy to off. Go back to the app page and download.
Enjoy.
Tell me if you have any problem.
