Or ha'Chayim (citing the Tosefta): 'If five partners Shecht a Korban, each one is obligated to perform Semichah, not all at once, but one after the other'. 1
See Oznayim la'Torah, who explains why the Tosefta derived this from this Pasuk.

See Pasuk 32 "Ve'achal Aharon u'Vanav, where he makes the same comment.
Where did Moshe Shecht the bull of the Chatas?
