name these 2 please

Their names are Anna aka Anna Bulkina, Anna Pivnik, Annette Bulkina, Any, Anya (on the left) and Alena aka Alena Alexeeva, Alena Lauri, Alyena Lauri, Alyona Alekseeva, Yaroslava_bi (on the right), here in a photo taken and released by Russian photographer Sergey Basovich (in Cyrillic Сергей Басович) in St. Petersburg around March 2011.

You can find OPs pic on the official account of the photographer on website Sight.Photo, uploaded under the Russian title "про масло и голеньких девченок" (google translates this to "about butter and naked girls") in March 2011:

There are a few more (solo) pics from this shoot on his account:

Notes:

In regards to their names:

1.) Anna (on the left)

As far as I can see, she's not credited by Sergey Basovich for this photoshoot, but she did many others that I found with pimeyes (restricted version). For examples, here she is credited as Anya by photographer Alexander Kuzmin for a series titled Hotter Than Cold, also released in 2011:

https://rainbook.livejournal.com/25871.html

And you can spot her here in several pics taken by photographer Arkady Kozlovsky:

I found the full names Anna Bulkina and Anna Pivnik attributed to a few other pictures that are collected here:
https://pikabu.monster/post/4244871-content
https://pikabu.monster/post/4805389-content

For the former full name, you can check the archived pages of her now deleted account on vk.com with lots of info. Searching for the latter full name, you'll find out that she's from St. Petersburg and did (nude) photoshoots during her university studies for a job/profession that has nothing to do with (nude) photography / porn. I don't want to link to this other job - that's all I'm going to research about her.

2.) Alena (on the right)

As you can see, Alena is credited in Cyrillic as Алена for her solo pics of the shoot by Sergey Basovich on the official upload. And - surprise - pimeyes associated her with a photo that can be found on the following request page:


https://forums.socialmediagirls.com/threads/alyona-alekseeva-aka-alena-alex
eeva-aka-yaroslava_bi-mfc-russian-hot-model.92679/

The photo was most likely taken around the same time as OPs picture (I assume she modelled between 2011 and 2015). She did many other shoots during this time - for examples, for Mavrin, Denis Goncharov and Alisa Verner:

https://vk.com/photo-43605395_311848540


https://en.alisaverner.com/gallery/art-portrait/65/

Since then, Alena not only did webcam shows as Yaroslava_bi on MFC - she also did a lot of "beauty operations" to her face and her body. In her current pics on instagram, she looks completely different - you can barely recognize her from her nude photo shoots... :-(

If you're interested - this is a recording of one of her webcam shows:
