Electronic – Help identifying SMD components

diodesidentificationintegrated-circuittransistors

I am having trouble identifying some components in this circuit. I am not sure if these are commercially available or not, so that's why I am asking.

The components are shown below:

  1. I believe this would be a transistor.

  1. I believe this would be a diode.

  1. Unsure.

  1. It has a marking like a diode, but really unsure if it is.

  1. I believe this would also be a diode.

Edit:

  1. Unsure about this component as well

Thanks to @Phil G who found both 4th and 6th to be dual transistors. And the meantime i found CY806(1st) to be 2SC881-Y and 5th to be BAS21-O3W.
But if anyone could help me with the 2nd and 3rd, it would be greatly appreciated

The SMD Codebook is a useful resource for identifying these, of the parts you show, I find UMH11TN for the third one, and BAS21-03W for the fifth one, but the marking in the datasheet for the last one doesn't accord with the marking in the database.
