In this time of kali, which human incarnation is to be worshipped?
 
Suppose you have identified some human forms as incarnations.  Now the problem comes; who is the real human incarnation among these? Suppose you have worshipped all so that the risk of missing the real human incarnation is avoided.  Suppose you have taken one form and it may not be real human incarnation.  Even then, you need not be worried. Such human form may not be God but certainly he must be a very close devotee of God. Since your filtration is to such high level, the other forms must be exceptional devotees of the highest level.  

Suppose you have taken such a strong devotee as human incarnation.  I assuredly tell you, that you are more lucky than the person who serves the real human incarnation. The reason is that God is more pleased if such strong devotee is worshipped, because God loves such strong devotee more than Himself. Therefore you will receive a better fruit in quicker time. Apart from this there is also the possibility of the same God coming in different forms in the same time. For example, Parasurama and Shri Rama and AkkalKota Maharaj and Shridi Saibaba were simultaneous human incarnations.
