You can then save as a title template and then drag it in to the timeline anytime you need. Note that the actual text and screen positions are also saved -- these will have to be edited for each object if needed. It seems you can't save and then load the fonts styles etc as video effects so you may have to redo existing titles. Next time do just one and save as a personal template to apply for the remaining titles
Carl's method is the most versatile, but in practice I always end up doing the same as Andreas. IOW, just copy the first title object and then paste it into the timeline when I next need another one of the same style.
I do the same as Andreas - copy and paste the first title object - however depending on the title object used the title will be centred on at the same position for all of them. You have to adjust the position if you want them all to start / be positioned at the same point.
