The connections are OK, the anode is common, the cathodes goes to the 4094. When the leds should light? When something ferrous / non ferrous is detected?

Thank Jap.

Another question. See the foto.

Are the same resistance or are different. I know that they are 10k but are the same material? or are metal film and the others ceramic?
The question is, can i use any of this? Is the same.
Thank you.
