Should I wait until they all upload the letters before I can submit the applications ?
Absolutely not. In fact most application processes recognize that this will not happen until after a student has submitted their apps. If you feel your LOR's are taking a bit of time, send them an email letting them know which apps have been submitted and are awaiting their LOR. Obviously you'r app wont be "complete" until then, but you can still get it in.
