These are also referred to as badges. You need to do all 5 of these on the assigned levels. If the level selection screen shows no badges then there is nothing required to do on that level other than finish it.

Score Badge- Beat the target score

Accuracy Badge- Usually 90% accuracy

Max Combo- You need to hit a certain combo to pass this, usually this can be done by hitting so many enemies with a perfect in a row but sometimes combos can be built by hitting so many enemies with an "ok" or "poor" multiple times

Continues- Simple complete the level without dying this is probably the easiest because even on thrasher difficulty if you just spam buttons you usually wont die.
