Yes, trilobites were still present in the Permian, but at much lower numbers and diversity. Only the Order Proetida remained.
The Permian ended with a mass extinction, and among the many groups which went extinct at the end of the Permian were the last trilobites.

No, trilobites are extinct marine arthropods that lived from the early Cambrian period to the end of the Permian period, around 520 to 250 million years ago. There are no living trilobites today.

Trilobites existed for about 270 million years, from the Early Cambrian period to the end of the Permian period, before becoming extinct around 250 million years ago. Each species had its own lifespan, but on average, trilobites lived for a few years to several decades, depending on the species and environmental conditions.
During the Permian extinction, numerous species went extinct, including nearly 96% of marine species and around 70% of terrestrial vertebrate species. Some of the affected groups were trilobites, blastoids, amphibians, and early synapsids.
The Permian was the last period of the Paleozoic Era, spanning 299-351 million years ago. It was a time during which reptiles diversified. It ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history.

Trilobites were warm blooded creatures that lived in the ocean from the cambrian period all the way until they were wiped out in in the permian period.
The trilobites went extinct during the mass extinction at the end of the Permian period.
Trilobites were associated with the Paleozoic era, from the Cambrian to the Permian.
The first trilobites lived in the Cambrian then lived all the way through the permian

Trilobites lived for 280 million years before they became extinct, from the Cambrian to the Permian.
Trilobites, and eurypterids (giant marine scorpions). Ammonites are not arthropods but molluscs.

Permian Period.
Trilobites first appeared in the Cambrian and were last seen in the Middle Permian.
The Permian Period,248 million years ago, was the largest extinction period on Earth. Ninety to ninety-five percent of marine species were eliminated, including fusulinid foraminifera, trilobites, rugose and tabulate corals, blastoids, acanthodians, placoderms, and pelycosaurs. Numbers of sharks and bony fish were drastically reduced during this period.
