Absolutley! Similies, alliteration, and personification are all literary devices that are used in writing.
Similies are comparisons using the words "like" or "as". For example, if someone said "the stars were shining like diamonds in the sky," he/she is using a similie because they are comparing stars to diamonds using the word "like".
Here are some more examples of similies:
After days without food, I was as hungry as a bear.
The star athlete was as fast as lightning.
The hurricane winds sounded like a jet engine.
Alliteration is when you use several words beginning with the same letter/sound in a row. Have you heard of "tongue twisters"? These are often examples of alliteration. For example, "Sally sells seashells by the seashore."
Here are some more examples of alliteration:
George gave gallons of gas to Gertrude.
Peter Piper picked a peck of pickled peppers.
Arthur Ashe was an amazing athlete.
As you can see, not everyword has to start with the same sound. Also, it can be as simple as two names that start with the same letter - such as "Bugs Bunny" or "Daffy Duck".
Personification is when you give human qualities to something that isn't human. For example, when someone says "the thunder screamed," they are using personification because screaming is a characteristic of humans, and thunder is not human -- or even alive!
Here are some more examples of personification:
The droplet of water danced at the end of the icicle as the temperature began to arise and melt away the ice.
Time raced away as Billy began his big final exam.
The dark gray car seemed to jump out in front of me just as I turned my attention back to the road.
