I am using a JST company's B2P-VH connector. I could not decide how i can place it to the edge of the PCB. Do you have any comments whether at the photo (1) or (2) is correct? Thank you so much.
You can reach the datasheet here.

You have a few things to consider.
Option 1 needs clearance behind it on the board to allow the locking tab to move.
Option 2 suffers from a higher probability the locking tab will break off due to catching on something or pulling sideways on the cable. However it does give the pins a little protection when the board is being handled. You also need to ensure there is room to unlock it when the board is assembled in wherever it is going.
If neither of those is a problem, you can chose whichever one you think looks best.
A different concern you may not have considered is, if, in the future, you decide to switch to the 90 Degree version, you will want that pointing off the board. As such you need pin 1 on the correct side, so I would use option 1.
