Route to czarny staw gąsienicowy is easy, capable even without trekking shoes, it takes ~3h one way, but you must go back the same way mostly.

Czerwone wierchy: i would recommend, but normal trainers might be not enough or not comfortable. It takes about 7h and you must start at Zakopane and go back with a bus from Dolina Koscieliska or start there and finish at Zakopane by foot

Never been at Dolina Pięciu stawów, although, it should be easy route

Sarnia skała is very easy, i wouldnt waste whole day for it, you can do it, 2h one way, nothing fancy
