Each paragraph should start with a topic sentence, which sets the reader up to understand what the paragraph will cover. Once stated in the first sentence, the topic is developed in successive sentences of the paragraph:

When there is a mix of items to be communicated in a paragraph, they need to be presented in a logical order (eg chronological, or their importance for the intended reader). There is no single ‘right’ way; it simply needs to be logical:
