1. переименуй пространство имен в Form2.h и подключчи его 123.cpp
2. как вариант попробуй определение класса Form2 запихнуть в файл Form1.h. в 123.cpp подключай только Form1.h
2. как вариант попробуй определение класса Form2 запихнуть в файл Form1.h. в 123.cpp подключай только Form1.h
Вынесите код Form1::button1_Click() и Form2::button1_Click() из .h-файлов в .cpp-файлы. На форуме полно примеров по вашему вопросу.
