Ref. No. 1045/41-217
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
Maximum 7 shares could be in a big animal slaughtered in Qurbani. In a small animal there must be only one share. A goat cannot be slaughtered in the name of more than one person. However, if a person offers a goat in qurbani in his name and sends its rewards to the persons mentioned above by you, there is nothing wrong in doing so.
And Allah knows best
