Could you post the lines of two and four so I could see what they look like?
The answer is 'trochaic tetrameter'. Trochaic because trochee consists of a sequence of first stressed and then unstressed syllables: SAY that HEALTH and WEALTH have MISSED me - words in capital letters are stressed, the rest of them are unstressed.
Tetrameter means that there are 8 syllables. One meter = two syllables. And tetra, meaning four, must have 8 syllables.
