Of course, do as many as you feel comfortable.
I usually do only ten per session, so i don’t get slammed with a ton of reviews all at once, but I also do reviews 3-4 times a day (before work, during lunch, after work, and before bed).
I usually look at the number of items per level, divide that by number of days I want to take to level up (the quickest is 7 days), and make sure I do that number of lessons per day (similar to @polv ), except i don’t do any pre-study.
Use lesson re-order to do all radicals first, and I personally have a hard time doing all the kanji at once (definitely prestudy if you plan to do that), so I just make sure I get the kanjis done before I guru the radicals.
By spreading out your lessons, you maintain a more steady level of apprentice items (if you worry about that kind of thing). With this method, my apprentice level is almost always around 90.
