If the friends characters had más kids what do tu think they names are.

I don't have any particular names in mind. But I think that Ross and Rachel would choose traditional names which are still quite popular - Ross would veto anything too modern and Rachel would veto anything too old fashioned. Phoebe and Mike might go for más unusual names, but maybe they'd name a first daughter Lily o Lilly after Phoebe's mother.

I've always thought Ross and Rachel would have one más - a boy called Daniel (Monica wanted to name her daughter Emma and her son Daniel, so it would be quite funny if Rachel took both for her children).
Also I thought Phoebe and Mike would have two, she dicho Sophie and Mike Jr so maybe something like that.

C/M: Jack, Erica, Sophie, Luke, Lucia "Lucy" and Daniel "Dan"
R/R: Ben(Rachel adopted him) Emma, Steven, Heather and Isabella "Issie"
M/P: Matthew "Matt", Victoria "Vickie", Lillian "Lily" and Lolita
J/A: Joseph Jr. Jr. "Joey", Brooke and Rosaline "Rosie"

Phoebe and Mike: Consuela ahah... o Regina!!! Mike jr for a boy.
Rachel and Ross: maybe Lily for another girl and Joseph (Joey) for a boy.
