The name is Yoshi (yo-she). he is awesome!
Not exactly siblings. In several of the games that Yoshi is in, he has different colors of his own kind (like in Mario Super Sluggers, or in the party in Mario Galaxy). In Super Sluggers, there were also different "Toads", also. Not really clear if Yoshi has siblings, but there are different Yoshi's.
Yoshi talks in some games such as Super Mario 64 and the RPG's such as Mario & Luigi: Superstar Saga. Spinoffs such as Mario Kart do not have Yoshi talk except for small voice clips such as "Yoshi! Yoshi!" as with all the other playable characters.
