What kind of phages are you talking about? My experience is with filamentous phages, M13- and M13-related phagemids, and the answer is YES, you can find colonies with more than one  plasmid inside after infection with phages.

Thanks dear Rojas

Are there any phage number limitations on the infection of single bacteria ? if yes, Why?

I dont know whether there is a limit, but in the techniques I routinely use we try to keep the ratio bacteria/phages as high as possible to reduce the chances of multiple infection. Thats why, although I have observed cases of infection with more than one phage, as I told you before, in general we have single infection and the link between genotype and phenotype of phages is maintained. The limit is thus imposed by probabilities.
