You are coming from Android?

Google refused to do apps for windows phones so you will not have any official apps that use Google services.
Search YouTube in store, there are some really good third party aps. For Chrome.... just use Internet Explorer it is really good and reliable on windows phone 8.1
You wull not be able to install any .apk on a windows phone (.apk works only with Android). WP uses .appx or .xap
And is better not to side-load apps from untrusted sources
