The last two examples are broken Turkish. Please use the first two examples. Gel + eyim mi? = means "should I come" Gel + elim mi? = means "should we come"

Merhaba Davood, In written language a) if you are writing to a close friend, very normal to use both 'geleyim' mi and 'alayım mı?' b) written&formal language; gelmemi istermisiniz? almamı ister misiniz? You always come up with interesting questions. Teşekkürler.

isn't it abnormal to use written forms in spoken language ?

Thank you dear jello

Yes they say "geliim mi, aliim mi? geliyom, alıyom" in spoken language. I even say so, tough I'm trying to pay attention to my pronounce. But there is a truth that it sounds unpleasant to ear. You use the written forms. Don't make reductions.
