I have to use and shift between English, Japanese and Korean at a moment's notice, as I need to speak and write all three as a part of my job. That leaves me room to mess my brain with 1~2 other languages I listen to on YouTube, or have occasional interactions with other language works/speakers, or so. So for the question "is there any room for more than three", I'd say the answer is yes.
Wow, that's very impressive! It takes me quite a while to "warm up" my Portuguese before I can speak it at my normal level of competency, it usually requires thinking in and/or listening to Portuguese for a few minutes at least to get back into the swing of it. That said, that's only the case if I've been speaking only English for a few hours (like at work, for example) - when I'm switching between speaking Portuguese and English every few minutes (or seconds even), such as at gatherings where there are speakers of both languages present, I don't find that particularly hard to do. I can't imagine having 3+ on the go at once though!
