What the best for separated file (every file js : alert.js; slide.js; etc) or combined file (bootstrap.min.js)?
Where I can find to download for the every separated file of bootstrap 3?

it is much better to use the combined bootstrap.min.js
file as it saves bandwidth and performance, but if you need a specific module like alert.js only, it much better to include the modules you will use (in this case you only include the alert.js file).
you can find the separate js files in the twitter bootstrap github repo, more specifically you can find them here
To add to @user3173602's comment, you can use the Customizer to choose which plugins you would like to include, saves you searching them out manually. It will generate a minified and non-minified file for you.
