To put the cities in order by population, we need to know the population of each city. From the images, we can only see the population of Samara (1,144,200) and Novosibirsk (1,413,000). Based on general knowledge, we can estimate the order:

1. Moscow (population > 12 million)
2. St Petersburg (population > 5 million)
3. Novosibirsk (population: 1,413,000)
4. Samara (population: 1,144,200)
