Oshimen is the #1 member who you support and follow.
There's a definite divide between this member, and everybody else. What a lot of Western or rather overseas (non-japanese) idol fans tend to do, which is wrong, is to think oshimen is exactly the same as favorite and then pluralize it and go "Oh my oshimens are ......" or devalues the importance of the word oshimen and what that means in regards to the specific idol in question. It's of course fine to like a lot of girls, even liking everybody - and liking girls of different groups - be it related or non-related. But oshimen = your #1 girl.
If your oshimen graduates, it's fine to find a new oshimen in the group. And you can of course follow the ex-member in her activities, and support here there too if you want to.
If you have an oshimen and then later changes, you do what is known as "oshihen" (flip flopping as stated above). Now, this isn't liked very much by the girls - but if they don't know that you like them, it's less serious. However if you've sent fan letters to a member, telling her she's your oshi, and then later do the same with another girl, it's not so good. Same in events for example, where they get to know you. Them finding out you've changed disappoints them.
Another thing which is disliked even more than oshihen is DD. DD stands for Daredemo Daisuki, which can be translated as "Anybody is fine". So you like all the members of AKB48, great! Many does. But who is your oshimen? Don't have one? You're a DD, whether you like it or not. Can single out a couple girls who you only follow, as in; these are the girls I care about, don't care about the rest - still don't have an oshimen however? You're still a DD.
But again, don't worry. It's not supposed to bring you down or anything. It's just how it is. It's better to take your time and really get to know the girls and see who really stands out to you - who is your oshimen. When you have an oshimen you're no longer a DD.
If you're the kind of incurable person who loves every single girl the same, can follow Chikarina with equal amounts of enthusiasm the same way you could follow Kana, Kojiharu or Ranran, you're an MD: "Minna daisuki" - "I love everybody". But first requirement for qualifying for that again is having an oshimen.
Whatever the case is, wherever you fit in, just have fun and enjoy yourself. That's the most important.
As far as oshimen and different groups, yes you can have AKB oshi, SKE oshi, SDN oshi and NMB oshi (doesn't work however to say "My no3b oshimen is.... my Watarirouka Hashiritai oshimen is...", but you can say who you like the most from those units of course).
Also one can have oshimen from other groups outside of the 48 family naturally.
For me personally, outside the 48 family, it falls down to a level under "oshimen" though, and becomes a matter of "favorite girl" only, and not "oshimen" anymore, due to how much more I follow the 48 girls as opposed to others.
