Well, when I saw Frisk, I decided Frisk is a guy. Not sure why tbh. There is, however, some evidence that Frisk might be either gender

1. “Flirt” is only an option against male enemies (excluding Toriel on the cell phone), suggesting Frisk is female;

2. ...but Frisk is usually a male name.

Chara, on the other hand, is harder, though I just decided Chara is female when I first saw her.
