"Get your own pen!" "It'll cost you!"

Here; you will need this on you gurney. It has saved my life and may who have come before me. May it be your protector also. Have faith in it's power and you will return in tact. Here; his name is kiloton. Keep him in the box during the day. Here; don't look at it. Just slide it in your pocket and forget you ever saw me. It's ok.

here you go here you are yes, you can borrow it

"here you are" ( a bit more formal, for us americans ) "here you go" (a very amiable and common way to say it) "here it is" (a bit less common, but still useful" "here" (very informal)

You can say "here". That is acceptable in most situations. You will sound foreign if you say "take" for two reasons. 1. "Take." is the command form of the verb, so it sounds like you are ordering the other person to take the pen. This can be considered slightly rude, especially since single word commands are often used with trained animals (e.g. sit, fetch, stay, give, etc.). 2. Take, as a command, requires a direct object. To be grammatically correct, you could say "take it" or "take the pen". For more formal situations, you have many options. A: Do you have a pen I can borrow? B: Yes. (while you hold out the pen) Alternative answer 1: B: I do. [this is short for "I do have a pen you may borrow."] Most of the time, nobody will expect or require that you have a pen ready to loan to them. On the other hand, if your boss or a customer at work were to ask you for a pen, you may wish to respond in a way that shows some deference. In other words, you may want to respond in a way that tells the person who asked for a pen not only that you have one they may borrow, but also that it is perfectly reasonable for them to expect you to loan one to them. A: Do you have a pen I can borrow? B: Certainly. [this is short for "I certainly do have a pen you may borrow."] Alternative answer: B: Of course. [this is short for "As a matter of course, I have a pen you may borrow." In this sentence, "a matter of course" or "of course" means that the statement coming after the phrase is inevitable or should not be argued. You are really saying, "Not only do I have a pen you can borrow, but it would be inappropriate of me not to grant your request."] Also, Sunrunner's Fire is a great book.
