Deleting an iCloud backup won't delete anything currently on the phone. But it shouldn't be necessary to delete a previous backup in order to do a new backup.

If I go onto settings and icloud and I try to manage my iCloud storage and I delete my last back up will that than delete some pictures on my phone because I’m getting a new iphone and I need this one backed up

If you are syncing the Photo Library to iCloud, your photos aren't in your backup.
Would I lose all my pictures if deleted my previous back up
