AJax Infit Scroll with multiple WP_Query arrays

Can someone Explain to me how we can add multiple queries into the compare?

// Create Filter Array
$queries = array('relation' => 'AND');

// Query Range
if (!empty($range)) {
    $queries[] = array(
        'key'	 	=> 'range_size',
        'value'	  	=> $range,
        'compare' 	=> '=',
    );
} 

// Query Bed
if (!empty($bed)) {
    $queries[] = array(
        'key'	 	=> 'bedroom',
        'value'	  	=> $bed,
        'compare' 	=> '=',
    );
} 

// Query Bath
if (!empty($garage)) {
    $queries[] = array(
        'key'	 	=> 'garage',
        'value'	  	=> $garage,
        'compare' 	=> '=',
    );
} 

// Query Garage
if (!empty($bath)) {
    $queries[] = array(
        'key'	 	=> 'bathroom',
        'value'	  	=> $bath,
        'compare' 	=> '=',
    );
} 

$args = array(  
    'post_type' => 'properties',
    'post_status' => 'publish',
    'posts_per_page' => $perpage, 
    'orderby' => $sort, 
    'order' => 'ASC', 
    'paged' => get_query_var('paged') ? get_query_var('paged') : 1,
    'meta_query'	=> $queries 
);

Currently have this, which doesnt work when applying queries

echo do_shortcode('
            [ajax_load_more 
            post_type="properties" 
            offset='.((get_query_var('paged') ? get_query_var('paged')*$perpage : 1)).'  
            posts_per_page="'.$perpage.'" 
            order="ASC" 
            orderby="'.$sort.'" 
            button_label="Load More"
            ]');
