Help sexing my mantis!

My fiancé and I have 3 mantis but we can’t seem to agree on whether each one is male or female. These are the best pictures we could get as they are small little guys (or gals). Please help us figure 

I’m not very good at this, but the 1st 2 look like males to me. I cant tell what the 3rd is tho.

Number one is male, number 2 is female, and we need a better shot of the entire abdomen for number 3.

Oops I uploaded the wrong picture.. is this any better for #3? 

And thank you both so much for the super fast and helpful replies!

Also, is it at all possible to identify species? #1 and #3 were both found in our backyard when they were super tiny in the beginning of May and #2 was found at my fiancé’s work a few miles from our house in June. 

I think the 3rd is female. 

Here is another picture of #3

Im now starting to think its male. Im not good at this so I would definitely wait for another reply.

I'm going to say male for number three. Number one looks to be Chinese, and I suspect the same for 2 and 3 but I need better front/top/side pics to tell for sure.

The 1st and 3rd look male, 2nd is definitely female. 

The 3rd is a male i think, what species they are, I dont know.

Nr 2 is female,1 is male

@MantisGirl13 does this little guy also look to be Chinese to you?  He’s the 6th one to wander into our garage this season but he’s quite a bit smaller and his coloring is very different from the others. 

Nope, that looks like a male Carolina mantis.

It's too compact and the head doesn't look like a European.

We don’t know what is going on but this is the 11th mantis to wander into our garage this year!

cute

Okay we could use all of your help again please!

So those that said #1 and #3 are males and #2 is female were correct..

#1 and #2 ended up mating and now we are trying to prepare for her to lay an ootheca. Her abdomen is getting very plump and we want to make sure we give her an appropriate habitat to lay...

What would that look like? What types of surfaces need to be provided? I’ve read that we should feed her a lot but about how much would that be? Is there any given timeframe for when she will lay? Any additional information about this process would be greatly appreciated!

thank you all again for all of the help!
