I am studying the efficacy of using a single feature for predicting a set of events (which is a multi-class classification problem). I was wondering if it makes any sense to use only one feature for multi-class classification. Thanks.

Yes! You can use only one feature for multi-class classification. For example, you have one feature height
and you want to classify short
, medium
or tall
.
