The classroom has 10 short/low chairs, 10 tall/high chairs, 10 small desks, 10 big desks, 5 windows, and 20 lockers.

I wouldn't use "short" but all the rest are fine.

Yes, you have used the correct adjectives in your sentence.

In order to determine if you have used the correct adjectives, we can compare the adjectives you used with their corresponding nouns.

For example, you used the adjective "short/low" to describe the chairs. This is correct because the adjective accurately describes the height of the chairs. Similarly, you used the adjective "tall/high" to describe the other set of chairs, which also accurately reflects their height.

You also used the adjectives "small" and "big" to describe the desks. These adjectives correctly describe the size of the desks.

Lastly, you used the noun "windows" correctly, without any accompanying adjectives. This is appropriate, as the noun itself is sufficiently descriptive.

Based on this analysis, it can be concluded that you have used the correct adjectives to describe the items in the classroom.
