The first line contains a mixture of 16th notes, 8th notes, and quarter notes, and the dynamic is p, which means quiet.
On the second line, there is a long crescendo, which means to gradually get louder. The rhythms are the same in both bars, so focus is definitely on playing the crescendo correctly.
On the third line, the dynamics increase to mf, which means medium-loud. On the second bar, there are rim hits on the snare drum, which is achieved by hitting the rim of the snare drum with the drum stick. This is not to be confused with a cross stick snare drum, which would be hard to play in relation to the rest of the bar.
On the fourth line, there is a mini crescendo from quiet to medium loud, which is then repeated exactly the same. The second bar with the divide symbol means to ‘repeat the previous bar’.
On the last line, the dynamics carry on as medium loud. There are accents (the arrows above the notes), played on the snare rim. This means to play the rim as before, but hit them a bit harder than normal.
