I have failed my theory driving test 4 times in 5 months can i keep taking it or do i have to wait?

You should have to wait, forever. 4 times you failed one of the easiest tests I know! You are not safe to be on the road. You do know cars can kill people, the test is common sense, if you don’t know what to do at a red light (stop) when a truck is turning left in front of you (slow down and wait) then you are not safe to be in control of a car end of.

If you haven’t learned any of the stuff for the test though then perhaps its explainable, although its still mainly common sense. Are you having lessons, if no then perhaps its that you can’t compute the test with real situations and so maybe a few lessons with an instructor could help you learn what you need to know. Take some months off, learn the highway code, learn the type of questions you’ll be asked, learn how to drive; then take your test. if you fail 5 times, perhaps you have to think driving isn’t your thing.

You can keep taking it, but I’d recommend you don’t. If you’ve failed four times already then there must be something you’re not doing right. Take some time to fully learn the Highway Code and practice on some hazard perception tests.
