My rule of thumb in the past has been that if you don't have at least three things that can go in a category, then you don't need that category. Each of these meets that criteria, so now we need to look at whether it's worthwhile to have each category. Obviously, you think so since you're asking if we can add them.

Doofenshmirtz's ex-girlfriends is a good one to have because it's a significant part of who he is as a person, though if we call it "Doofenshmirtz's girlfriends", it will match more closely with the "Doofenshmirtz girlfriends images‏‎" category. We can explain on the category page that it includes people that were his girlfriend at one time or he simply dated.

"Episodes focusing on other characters" would be for the fourth one you listed. If Dan and Swampy are going to make a special effort to have an episode where Phineas and Ferb don't have a leading role, that's worth noting with a category. Likewise, something like "Episodes in other seasons", for something other than summer, is worthwhile.

The other three are okay, too. Go ahead and add these.
