Would these sentences be correct with these phrases?

RUNNING LATE

1) I'm so sorry, but I was asleep and now I'm running late

2) The bus hasn't come yet so I'm running late. If you want too, buy the tickets

GOT TIED UP

1) I couldn't call her back because I've got tied up checking my son´s homework

2) He is tied up looking for a cheaper rent house although I think that he's able to help you with that  (this is okay, but I would say "busy" rather then tied up.)

RAN OVER

1) I forgot to push the bus button and the bus driver went past my bus stop.

2) Although my work time has run over, that extra isn´t paid.  (this sounds strange, I would say "even though I do/did overtime, the extra isn't/wasn't paid)

I would generally only use the term "ran over" to say that I have actually run over something, say in a car, or to finish off something, like by saying "We have run over time, we will have to finish now"

Are these phrases (running late, got tied up, ran over) commonly use in daily conversation? Do they sound natural?

THANK YOU!!
