What are those five pages? They could be from your extensions telling you what the newest updates are, or you could have malware which corrupts your homepage and often spawns annoying pop-ups, ads and other annoyances. If they are extension update pages, simply close them down. If this happens every time you open Chrome, then Chrome itself has been corrupted. Uninstall, reboot and reinstall it again to fix this problem.
32b version:
Get 32b free web browser
64b version:
Get 64b fast free web browser
Download the 32b version if you know you only have 4 Gb of RAM or less. If you know you have more than 4 Gb, try the 64b version as it's faster. If you are unsure which one to get, go with the first one. Running a 32b version on a computer with more than 4 Gb of RAM only means that version of Chrome will only utilize a maximum of 4 Gb regardless of how much actual RAM you have. But a 64b version will use the full available RAM and not be limited to 4 Gb only.
If the pages are nonsense and nothing you wanted or had interests in, then it's probably malware changing your homepage. To clean malware install a malware blocker/cleaner like, "Malwarebyte's Anti-Malware (MBAM) software and let it run. If it finds malware it will report it and give you the option to remove, clean, quarantine it. Or CCleaner. Both have free version of their programs.
MBAM is easier to use, while CCleaner is better it can also be destructive if you turn on the wrong settings. If you're a newbie go with MBAM. If you have some tech sense try CCleaner.
I myself use the MBAM Pro version which includes active 24/7 cleaning while the freebie version only detects stuff when it is ran. Though I read they came up with a freebie active detector for users of their freebie program called, "Malwarebyte's Anti-Exploit", which protects your browser from current and future malware.

To help with future problems in Chrome, you can install Chrome protection modules (Extensions) from their Extension/APP store. Left click the three stacked bars in the top right corner of Chrome. Move the pointer down to, "More Tools", and left click. A sub menu will open. Move pointer down to Extensions. A new tab will open to display any extensions you may have. At the bottom of that page is the link, "Get More Extensions", to go to the Extension/App store. No not the Google Play store... it's a different store. Or you can copy and save this direct link:
Chrome Web Store
In the search box look for Ad Blockers like: AdBlock, AdBlock Plus, uBlock, uBlock Origins. Click to read about them and install one. You only need one. Don't install more than one ad blocker. There are dozens of different ones, but AdBlock and uBlock / uBlock Origins are the most popular ones. They will help stop future attacks from malware sites but not fully protect against them which is why you need to run the malware protection program once a week/month on a regular basis.
