You could do it with just one for loop:

$groups_name = 
['jhon' => 20,
'aliza' => 30,
'rehana' => 40,
'adiba' => 50,
'black' => 1000,
'white' => 7500,
'red' => 3500];

$inputs = [50, 70, 4500];

function get_names($array, $input){
    foreach ($array as $name=>$value) {
        $target = abs($value - $input);
        if(in_array($target, array_values($array))){
            $pair = array_flip($array)[$target];
            echo "($name, $pair)";
            break;
        }
    }
}

Result:

get_names($groups_name, $inputs[0]); // (jhon, aliza)
get_names($groups_name, $inputs[1]); // (jhon, adiba)
get_names($groups_name, $inputs[2]); // (black, red)

Please make it minor update:

$groups_name = 
['jhon' => 20,
'aliza' => 30,
'rehana' => 40,
'adiba' => 50,
'black' => 1000,
'white' => 7500,
'red' => 3500];

$inputs = [50, 70, 4500];

function get_names($array, $input){
    foreach ($array as $name=>$value) {
        $target = abs($value - $input);
        if(in_array($target, array_values($array))){
            $pair = array_flip($array)[$target];
            echo "($name, $pair)";
            break;
        }
    }
}

Result:

get_names($groups_name, $inputs[0]); // (jhon, aliza)
get_names($groups_name, $inputs[1]); // (jhon, adiba)
get_names($groups_name, $inputs[2]); // (black, red)

work only for two values
please make some change in it if input vale is 120 then

output ( Adiba   Rehana   Aliza )

if input vale is 1120 then

output ( Adiba   Rehana   Aliza   Black )

if input value is not match in given array
then show msg not fount
