Option 2 These are my variant of analyze I hope I revealed the main idea of these poems, enjoy.
1. A. Pushkin. Autumn.
Autumn for Pushkin is the time to rebirth while everything around is dying(природы пышной увяданье) and saying its goodbyes. The main associations are the golden-red leafs on the trees falling to the earth. Also in this verse Pushkin is comparing autumn with the others times of year and here I consider one another advantage for of autumn for Pushkin.

2. Tutchev – Есть в осени первоначальной I took this poem because I liked it more than your variant, sorry for that.
Tutchev in this poem tried to express the processes in weather changing while autumn, in other words he tried to show how earth is preparing for the winter (Короткая, но дивная пора) , but he also described autumn as beautiful period (Весь день стоит как бы хрустальный, и лучезарны вечера)
3.A. Apukhtin

4.E. Bargrizky
Author pays more attention to the people’s living while the autumn is going. Autumn is time for harvest and it is disitinctive feature of the autumn for the author. There are also lines dedicated to the yellow grass of yellow fields etc.
5.S. Yesenin

But anyway he is not man of autumn. As I feel, Yesenin is the man of early summer when the spring’s just gone. 6.I. Bunin
For Bunin autumn is the last part of summer. Autumn is herald of the winter too. In the day light it’s red and yellow, showing what summer has made and in the night all the thing become dark and blue telling about what coming
