Hi JF
You can make two wishes at a time but not too many if not your nobleman may get confuse and overwork.
Ooops….I just saw something.

Your boyfriend has another nobleman star which is the Horse South2 direction 172.5 to 187.5 degrees. Since there is a Horse in his bazi, he should invite the Horse instead of Tiger, in this way it will be more speedy to receive the nobleman help. Can you please ask him to change to the South2 direction for better result. I am so sorry to overlook into this and please accept my apology. Sorry, sorry, sorry (you like the Korean song?)
As for your case yours other nobleman is the Rabbit East2 82.5 to 97.5 degrees but since your bazi does not have both the star it may take time for the nobleman to assist you. Something like for your boyfriend his nobleman travel by car and for your case it travel by bicycle.

Need to be patient and you will see result.
Bernard
