I’ll take a guess and say that you made an error in the format. It worked by adding one at a time with a new function and its working fine after following their plugin code:

<?php
add_filter( 'if_menu_conditions', 'my_new_menu_conditions' );
function my_new_menu_conditions( $conditions ) {
  if (function_exists("EWD_FEUP_Get_All_Users")) {
    $conditions[] = array(
      'name'    =>   __( 'FEUP is logged in', 'if-menu' ),
      'condition' =>  'if_FEUP_is_logged_in'
    );
  }
    if (function_exists("EWD_FEUP_Get_All_Users")) {
    $conditions[] = array(
      'name'    =>   __( 'FEUP Level 1', 'if-menu' ),
      'condition' =>  'if_FEUP_Level_1'
    );
  }
  return $conditions;
}

function if_FEUP_is_logged_in() {
          $CheckCookie = CheckLoginCookie();
          $currentUser = $CheckCookie['Username'];
          if( $currentUser ) return true;
          return false;
}

function if_FEUP_Level_1() {
          global $wpdb;
          global $ewd_feup_user_table_name, $ewd_feup_levels_table_name;
          $FEUP = new FEUP_User;
            if($FEUP->Is_Logged_In()){
            $Level_ID = $wpdb->get_var("SELECT Level_ID FROM $ewd_feup_user_table_name WHERE User_ID='" . $FEUP->Get_User_ID() . "'");
            $Level = $wpdb->get_var("SELECT Level_Privilege FROM $ewd_feup_levels_table_name WHERE Level_ID='" . $Level_ID . "'");
            }
          if( $Level == 1 ) return true;
          return false;
}

Try the below. I quickly wrote it, it should work in theory. But im sure there is a better way.
You’ll need to add a different condition for each user level…

let me know if it works

add_filter( 'if_menu_conditions', 'my_new_menu_conditions2' );
function my_new_menu_conditions2( $conditions ) {
  if (function_exists("EWD_FEUP_Get_All_Users")) {
    $conditions[] = array(
      'name'    =>  'FEUP Level 1', // name of the condition
      'condition' =>  function($item) {          // callback - must return TRUE or FALSE
          global $wpdb;
          global $ewd_feup_user_table_name, $ewd_feup_levels_table_name;
          $FEUP = new FEUP_User;
            if($FEUP->Is_Logged_In()){
            $Level_ID = $wpdb->get_var("SELECT Level_ID FROM $ewd_feup_user_table_name WHERE User_ID='" . $FEUP->Get_User_ID() . "'");
            $Level = $wpdb->get_var("SELECT Level_Privilege FROM $ewd_feup_levels_table_name WHERE Level_ID='" . $Level_ID . "'");
            }
          if( $Level == 1 ) return true;
          return false;
      }
    );
  }
  return $conditions;
}

add something like this in a functions.php or in a plugin.
It’s not perfect, but it allowed me to demonstrate the functionality for my friend. I’ll return to this later to clean it up, or wait and see if the devs of the plugin will add this into their code. Hope it helps

add_filter( 'if_menu_conditions', 'my_new_menu_conditions' );
function my_new_menu_conditions( $conditions ) {
  if (function_exists("EWD_FEUP_Get_All_Users")) {
    $conditions[] = array(
      'name'    =>  'FEUP is logged in', // name of the condition
      'condition' =>  function($item) {
          $CheckCookie = CheckLoginCookie();
          $currentUser = $CheckCookie['Username'];
          if( $currentUser ) return true;
          return false;
      }
    );
  }
  return $conditions;
}

I ended up using the “if menu” plugin and added the FEUP option into that.
So I can easily select menu options from the admin.
