Ok, some of those are ads, some aren't. With the notification panel swiped down, long-press one of the ad ones (like the cruisecritic or opinionshareresearch one), and tap App Info. Which app is giving you the notification?
I'm guessing it's your browser. There is an option in the browser to allow notifications from specific websites. It's possible you happened to be on one of those websites (probably as a popup ad) and inadvertently accepted notifications. You can get rid of them by opening the browser, tapping Menu>Settings>Site settings>Notifications, and look at the Allowed list. If you find sites there that you don't want notifications from, tap them, then Notifications, then turn off the notification toggle for that site (or tap the Clear & Reset button).
