In 410 AD, the Celts did not abandon England; rather, this period marked the decline of Roman authority in Britain. The Romans withdrew their legions to defend against invasions in other parts of the empire, leaving the Celtic tribes to manage their own affairs. This led to increased instability and conflict among various groups, including the Anglo-Saxons, who began to migrate into Britain. Thus, while the Celts remained, their societal structure was significantly impacted by the Roman withdrawal and subsequent invasions.

It is not known. Your question is extremely broad because there were many Celtic groups and the Celts were originally the biggest ethnic grouping in Western Europe. The Romans fought against many of them. They were attacked many times by the Gauls of northern Italy, who were, Celts and then fought them and conquered them in the 3rd century BC. They fought the Gauls of Gallia, who were also Celts, in the Gallic Wars (59-50 BC) when Julius Caesar conquered Gaul and in subsequent Gallic rebellions. Julius Caesar also carried out two expeditions in the southeast of England, which was inhabited by Celts. The Romans fought against the Celtiberians, the Celts of Spain, in the 2nd century BC. They fought against and conquered Noricum (most of Austria and Slovenia) which was inhabited by Celts, in 16 BC. They conquered southern England in 46 AD, Wales between 48 and 79 AD and northern England in 78 AD, all of which were inhabited by Celts. They pushed into Scotland a number of times, but withdrew and the Picts (Celts) of Scotland raided Roman Britain for centuries. As you can see from the above, it would be very difficult to estimate the number of Romans who died in many centuries of fights against Celtic groups.
