How do I remove notifications from my lock screen?

Hello.
I moved from Galaxy5 to iPhone.

I don't really like to get all the Notifications of messages and whatsapp groups on my lock screen.

also the phone is ringing while i get a text: I got used that when i get a sms or whatsapp the phone is not ringing and the lock screen is not opend also.
It's possible to do that on iphone? :)

You can adjust the settings for notifications in Settings > Notifications > INCLUDE. Here you can chose what/how applications send notifications.
