Two Tarantulas, What sex are they?

[MiaWolf42]

I'm guessing boys? But I've never tried to do this on my own. I've just read a very long article about it. Hoping someone more experienced will know.

Here's another of bottom tarantula.

These are good photos for ventral sexing. Both ventrals indeed indicate males.

Do you think the molt is a male too?

From the molt photo it is a little tougher to say. Firstly, it is an angled shot. I did download the photo and zoomed in, but pixelation is limiting. Nevertheless, I don't see spermatheca or an external uterus, which would be visible to the naked eye at this size; thus, consistent with male. A close up photo of the book lung region (excluding legs and cephalothorax, and not an angle shot) with spider's anterior-poster axis pointing north and south would allow a more definitive answer.

Agreed. I should have used my good camera. My brain wasn't functioning that day, so much going on. I no longer have the molt, so I'll wait and post better photos. Thank you for trying!
