applications - Is it possible or not?

My question goes like this. As we know playstore has great no. of applications and we need to use many of them. but if we install many apps at a time phone becomes too slow. so we install apps only when required and later remove them but we store all backups on sdcard.

now for eg. i have backup of an app say mx player and its version is 8.4.32 but in playstore current version is 9... and other backups also have higher versions in playstore. is there any app or way to update all the backup file to current version available in playstore.
