中文课 晚上 很 晚 下课。The Chinese class finishes late in the evening.

I think "很晚" means "too late", so I think the best tranlation is "中文课下课晚了"

星期二 朱 小姐没 有 课。Ms. Zhu doesn't have class on Tuesday.

i think it would be better translated like"朱小姐星期二没有课“。We always put the person as the begining of a sentence,it's different from English.

lecture cant stand for the class

we will listen to a lecture: 我们要去听一个讲座/演讲.

i think "lecture" is more academic than "class"...

Yeah a lecture is more formal than a class. Usually a lecture has 40+ students and is in university (or professional association), whereas a class has <40 students and can be in university, high school, middle school, training center, etc…
