Yorkies are yorkies.
There's only one breed, no standard or miniature. Check the Yorkshire Terrier breed standard on the Kennel Club website.
I show & judge some breeds so do know.
They do vary enormously in size though. This is because they were bred from much larger terrier breeds including the Skye ( I have those as well) Clydesdale & Paisley terriers, both extinct now, & so you often get a size throwback as being a relatively new breed ( only a hundred & fifty years or so, not centuries old like many breeds) the breed isn't reliably set yet.
The top weight limit for a show Yorkie in the UK is 7lb. But lots of the bigger ones make wonderful pets, especially where there are children.
Your little ones are lovely. If you aren't showing size doesn't matter at all.
