Of course. Kodaka is not able to make a single friend, because everyone falls for him.
The ideal definition of friendship:
"A true friend loves you unconditionally; he or she does not maliciously use, misuse, or abuse your trust to satisfy his or her selfish interests.
A true friend sticks around through good and bad times to the extent where friendship survives the test of time. You can readily trust, count, or depend upon a true friend without inquietude. By contrast, false friends expertly sweet talk their way into your life to satisfy their selfish interests because it's all about them and their needs. They are nowhere to be found when you need them the most, and they are adept at crafting excuses to make themselves appear supposedly "dependable." If you are a false friend, you can begin to make positive changes in your behavior from this second onward and progressively become a better friend to your friends."

If you read this and compare it to the way the Haganai characters approaches others then I can only see Kodaka fulfilling this definition perfectly (and perhaps Sena).
