4.4.4 Apps on 5.0

If I update to Lollipop will I still be able to use apps from previous versions or do i have to wait for them to update their apps to support lollipop?

Most apps are "backwards compatible." You shouldn't have any issues. The devs who create some of the most popular apps will update as necessary.
