Should I put some tarp on my ridge in the mean time in case it rains?
How would I attach the tarp? Duct tape?

With tile roofs the primary waterproofing is provided by the
underlayment. It looks like your ridge tiles blew off because they were
mortared in place - a common failure when the mortar is incorrectly
applied during initial installlation. If your underlayment is in good
shape (not cracked or torn) then you don't need to do anything for now.
Since the underlayment will degrade with long term exposure to the sun
replacing the ridge tiles promptly would be a good idea - this time use
an adhesive attachment such as PolyPro or even RT-600 (assuming the
mortar pads are still in place). If you replace all the ridge tiles it
probably won't be necessary to get an exact color match.
