Our project consists of (5 townhouse + multipurpose room). This is considered as one building.
townhouses are 3-5 floors and each is served by 1 AHU = total 5 AHUs
The multipurpose room has its own AHU.
The townhouses are not typical.
Is it sufficient to take one sample for each townhouse + 1 for the multipurpose room = Total 6.
following the guidelines, each floor of each town house must be sample, which means 4-5 samples must be taken per townhouse since the AHU is serving multiple floors. ??

Based on our testing experience, your interpretation of the guideline is correct. "In each area served by a single air handler, samples must be collected for each 25,000 square feet of floor space, or each contiguous floor space....". Each floor must be sampled to comply with the credit requirements. Only in situations such as schools, dormitories or hotels have we seen "identical" rooms be sampled under a different protocol but even in those cases that did not eliminated the requirement for at least one sample per continuous floor.
