Definitely a cuckoo wasp (Chrysididae)

Not sure about the genus
Not really a wasp but a sawfly (and they won't sting you with that tail, it is an egg laying tube).
Some type of horntail

Try Urocerus flavicornis or U. gigas (I'm not sure of the difference - I know that they were once considered the same species).
This is actually in the family Ichneumonidae.

Hi Veronica
This is a hover fly in the family Syrphidae.

Many of these are bee and wasp mimics.
Maybe an Eristalinus species. Have a look at this page.

Wasp - family Vespidae
https://en.wikipedia.org/wiki/Vespidae
Wasp.
Note how the wings are folded lengthwise down the middle. This doesn't always work, but when you see that it is a good guess you have a wasp in the family Vespidae (which include among other things the social wasps).

Mud dauber wasp - genus Sceliphron

Hover fly in the family Syrphidae

Lots of these look like bees or wasps.
This might be the genus Eristalis (just a guess - I am not a fly person).
