Erik Kalinak started as social media manager for SMER (the pro-russian party that got to power recently) and is now climbing the career ladder in SMER at amazing speed quite obviously being pushed as future prominent member of the party. His uncle is Robert Kalinak - one of the founding members of SMER.

Uhrik was elected a member of the European Parliament for the far-right neo-Nazi LSNS party. Later he founded his own party, the far-right and neo-fascist Republic. This was after the head of LSNS was sentenced to four years for propagating nazism - the Republic essentially is a continuation of LSNS. Uhrik is also very anti-Ukraine from the very beginning of russian invasion. You might remember him from 1st March 2022 when he completely ignored Zelensky's speech in European Parlament browsing his phone.

The other two names are more surprising, but mostly because they are kind of irrelevant. If russia spent any money on these two, they could as well flush it down the toilet.

Miroslav Radacovsky is pretty much nobody. I still don't quite understand how he got elected to European Parlament. The MEP elections are very much ignored in Slovakia. People aren't interested in participating, so the results are kind of random sadly. Anyways you'd be hard pressed to find anyone in Slovakia that would be able to tell you who Radacovsky is or to tell you single member of the Slovak PATRIOT party - AFAIK they didn't even attempt to run for a seat in 2023 elections. As you can guess they are a bit far-right, but it's hard to tell for sure.

Jan Carnogursky is no longer active in politics for over a decade AFAIK. FWIW he expressed some support for Putin recently, which is somewhat ironic, considering he was anti-communist in Czechoslovakia and was also imprisoned by the regime. but again, these days he's not relevant at all.
