Yes.

yes any male will do. they are all good at pollination it will be interesting to see what the berries [babies] grow up to look like. do you intend to grow them to see? or is it just to have berries for the birds.

Thank you for your replies and I am happy to hear that any male's can fertilise the female holly! I am not sure what colour the berries should be but I am going to be over the moon with any.
I have rescued the female plant from a small pot behind some old cottages next to mine, the plant was on its last legs just over a year ago, I have chosen a new main leader branch and tied it up into a vertical position to replace the dead head from the original, this year it has some obvious female flowers and I now have found a small male plant that is now next to his new girlfriend !

Glad to hear something's having an interesting life, even if it is plants, lol. Hope the berries are plentiful too.
