have on – tłumaczenie phrasal verb

I told James I saw his wife in a bar with a young guy. He was mad when he realised I was only having him on.

I hope you're having me on. I don't know what I'd do if our factory closed.

Okay, so I was only having you on when I told you I was emigrating. I was curious to see your reaction.

I'll text you later. I don't have my phone on me right now.

I thought I had a pen on me. Could I borrow yours, please?

I don't have my credit card on me, so I'll pay in cash.
