How to attach "diode AND gate" and "diode OR gate"

 

Attach to what?

 

The two schematics are correct as far as they go. What do you want to do with them?

Connect the output of one to an input of the other. Each diode gate loses some voltage, so you cannot string many of them together.

My question is how to join a 'and gate' and a 'or gate'.

 

Connect the output of one to an input of the other. Each diode gate loses some voltage, so you cannot string many of them together.

Then should I make transistor gate to create complex logic gate

 

Yep. Trasistors can restore the signal with each gate.
