Names are tough in this one, as they are full multi-syllabic Japanese ones, not shorter ones that are easier for Westerners (Also, as Japanese go last name first, and will usually address someone by their last name, we can find it more difficult). In case this helps, so far you've got (last name first):
Gojo Satoru (coolest ever)
Yaga Hasamichi (headmaster)
1st Years
Itadori Yuji
Fushiguro Megumi
Kugisaki Nobara
2nd Years
Zenin Maki (weapons user)
Inumaki Toge (cursed speech user)
Panda!
Okkotsu Yuta (who was referred to in this episode, but you haven't met him yet)
