I live in country where it snows, so can you combine prayers if it is -2degree outside and if the people feel the cold and the imam says its cold and we will combine but you are planing to stay in the masjid or near the masjid after Salah anyway so can you join them in the combination of the pray

Imam Ibn ʿUthaymeen said in ash-Sharḥ al-Mumtiʿ: If someone were to ask: What is the limit of “severity” and “cold”? The answer is that what is meant by a strong wind is that which goes beyond what is customary. As for an ordinary wind, it does not permit combining the prayers, even if it is cold. And what is meant by cold is that which causes hardship to people. If someone were to ask: If the cold becomes intense without wind, is it permissible to combine the prayers? We say: No, because intense cold without wind can be warded off by wearing extra clothing. But if there is wind along with intense cold, then it penetrates the clothing. As for strong wind without cold, then there is no combining, because strong wind without cold does not involve hardship.
