I need a proper translation for a project. I've used several different translation websites, but I got varying answers. What is the right translation? And how would I know for sure?

I've looked up a few online translations but they're all different. Can anyone give me the proper translation?

Correct me if I'm wrong, but the proper translation from Greek should be "Yeshua"....am I right or wrong?

I would appreciate if anyone knew the translation for the God is love in ancient greek. A friend is getting a tattoo and needs the proper translation as to not look like an idiot

Greek Translation?

I have seen the last name Kolokotrones also written as Kolokotronis. Which is the proper translation from Greek? Would they both be written the same way in Greek text?
