Troika Card Moscow

Hello Everyone,

Me and my wife are in Moscow and want to use the Metro, today I visited the semenovskaya station and the lady at ticket counter who only spoke russian gave us 4 cards. I think they are usable for one trip each. Where can I get the ones that I can use for a few days? Or how do I tell the lady that I need that one.

Also can these cards be used for buses and trams? If yes what apps that are available in english I can use to check for bus and tram routes similar to Yandex Metro for trains.

Thank you.
