To greet a male professor during the day in French, you can say, "Bonjour, Monsieur [Last Name]." If you are on familiar terms, you might simply say, "Bonjour, Professeur." It's polite to use "Monsieur" or "Professeur" to show respect. A warm smile and a nod can also enhance your greeting.
You greet people with a kiss on the cheek (or two, three, up to four) when you have a special relationship with them (friendship, family). There is no special reason for that, this is the way people do it here (just as Americans and their hugging, which seems weird to the few French who know about it). Men just shake hands of their male friends.
The way to greet a female friend in Italian is Ciao!("Hello!"), which also works for a male friend.
In Spanish, "professor" can be translated as "el profesor" for a male professor and "la profesora" for a female professor. The article used depends on the gender of the individual being referred to. Thus, use "el" for a male and "la" for a female professor.

Profesór is the spanish word for male professor. Profesora is a female professor. Maestro/Maestra for teacher male/female. "Tengo un profesór" means I have a [male] professor. "Tenemos un profesór" means we have a [male] professor. The spanish word for male is masculino. "Tengo un profesór masculino" would be a redundant statement that repeats itself redundantly over again.
