So often, the answer for multiple apps crashing is to wipe the device and start fresh with a factory data reset. That will leave you with the phone as it came from the box two days ago. Yes, it takes a good deal of time, but you've had the device a short time. It'll take a lot longer to get the phone restored later, after you have it set up the way you want it.
After you do that, resist the temptation to restore from a backup -- set it up as a brand new device. It's possible that your issue was caused by bad data transferred from your previous device. Add or set up your apps one at a time, then test them before adding another. If there is a problem with an installed app, you'll be able to isolate it.
