Oh, dude, Multiple bar charts are like when you have more than one bar chart in a single graph, showing different data sets side by side for easy comparison. Component bar charts are basically the same thing, just a fancy way of saying each bar is made up of smaller components representing different categories within the same data set. So, like, they're both just different ways to visually represent data with bars, but with a little extra flair.
It seems that you're not the only one asking that question because an answer has already been posted somewhere

You can only use the component bar chart when you have complete information. For instance, you must have totals and components to use the chart.
A composite bar chart is whereby each bar displays multiple data points stacked in a single row or column. On the other hand multiple bar graph are usually placed side by side and use different shapes to contrast between them.
This is used to represent the relative size of the components.

A bar chart is a series of vertical or horizontal bars, varying in height (or length) to reflect the value of each piece of the data on which the chart is based. In the case of a line chart a dot is placed at the same height as each of the bars and the dots are connected by a line.
