Cattleytonia Why Not and Sheaths Questions

[c123anderson]

First picture: I'll start out with my Cattleytonia Why Not. It's the first time blooming for me. Its one flower centered on the picture decided to bloom upside down.

The next two images are my Brassocattleya Theresa Ricci. It looks like one image is a sheath. There is a second image of Bc. Theresa Ricci.

→ Question 1: is the second image a sheath?

→ Question 2: how long should this be in sheath? It's been in sheath since the end of May, which doesn't seem right.

The last two images are my Laeliocattleya Green Veil x Brassia nodosa.

→ Question 3: is this in sheath?

I'm still a Cattleya newbie, so I'm thrilled to share new flowers and still not sure what to expect with my Catts.

Thank you for any help. If there are resources on the web, please direct me.
