In order to use the console you need to bind a key to the Developer Console in the Keybinds section, this bind is at the very bottom of the list.

ALL commands must be wrote in one of the following ways:

• command
  
• COMMAND
  
• Command

most commands follow this structure
commands can have more than 1 parameter, i.e.
this command should give you 3 weapons this structure can be expanded for more than 3 parameters

in order for the command to work something must separate the parameters from eachother, that can be anything from letters to symbols as long they are not numbers you could i.e. and it should work just fine
this can be used on any command, commands that add to a number will add the parameters at a time i.e.
this should add 90 shards

if you haven't played the game that much ence you saw like 4 weapons, I suggest you to play the game and see the weapons yourself, seeing them using a console command can ruin the MAGIC of finding out by yourself, although that's my opinion, you do you.
