Bom dia is the standard greeting used among Portuguese people during the day.
Como te chamas? is used to ask the question: [What's your name?]. The word como means [how] and the word te means [yourself]. The phrase translates more literally to something like [How do you call yourself?].
Chamo-me ... is used to say [My name is...], but the literal meaning is closer to [I call myself ...].
In Portuguese, the words eu and tu are the pronouns for [I] and [you] respectively, but in practice, these pronouns are often omitted.
Prazer literally means [pleasure]. The expression Prazer is short for [It's a pleasure to meet you].
