Can apply to multiple at one univesity. Usually it is unwise to apply to multiple from the same faculty, as in your case. But it's worth sending an email to the admissions tutor- they're the only people that'll truly know.
If you're interested in similar courses then contact the uni directly and ask if transfer between the options is possible and/or simple to do.
In 99% of cases listing more than one choice at a university is a waste of a choice - either the university would have reconsidered you for the alternate courses anyway (either automatically or on your request) and if not then you'll have watered down your PS and dedication to one of the subjects by making it clear that you're unsure.
Pick your favourite for each uni, talk to them to ask them to consider you for other choices if you don't get an offer/meet your offer for your first choice course, use your other choices to apply elsewhere and explore all of your options
Its worth checking with the Uni as sometimes they give what are essentially the same course but with a couple of different module options, different titles so they might get more applications. Therefore it might be actually 'worth' only one choice, and once accepted you choose which pathway you want to follow. Phone the Uni and double-check.
This happened a few years back with some Art & Design courses that were actually the same course but had been marketed as ' with Ceremics, 'with Textiles' etc etc , making it look as though there were 5 separate courses.
